Why Does 45 Degrees Maximum Range

The projectile launched at 45-degree does not win in either category yet the fact that it is able to place a strong showing in each category contributes to its ability to achieve the greatest range. When somethingis shot above 45 degrees gravity pull down on the.

Pin On Phy 111 Week 5

Adding the angles would be like rotating the hill to make it level.

. How do you get this. Now range is basically your displacement along X-direction. Notice that 5 degrees goes the same distance as 85 degrees.

2 θ 0 90 0 o r θ 0 45 0. 2theta 90 degrees. Sin45 Cos45.

Why does 45 degrees give maximum range. Yet since they involve the use of calculus they are not presented here. 90 degrees for maximum altitude and 45 degrees for maximum range.

This answer can be determined by inspecting the trajectory plots in Figure 1. Have you ever wondered why 45 gives you maximum rangeDid you know that for every angle of launch there is another angle that gives you the same rangeIn th. Think about it like this a 90 degree shot will get you the most hangtime and a 0 degree shot will get you the most forward velocity.

Gravity is pulling down on the object. First just to be clear what is projectile motion. At this angle the range is 163 meters - read from the graph in Figure 1 and listed in the fourth row of Table 1.

In a perfect system frictionless vacuum 45 degrees will always be the maximum range. Casco Associates a company. A projectile in other words travels the farthest when it is launched at an angle of 45 degrees.

This information is brought to you by M. Thus the horizontal range of a projectile for a given initial velocity is maximum when it. TextHorizontal range of a projectile dfracV_02sin 2thetag Where V_0 initial velocity theta angle of inclination g acceleration due to gravity Clearly the range will be maximum when sin 2theta 1impliestheta 45circ.

An example would be hitting a. The textbooks say that the maximum range for projectile motion with no air resistance is 45 degrees. The maximumdistance you will get is when theta is 45 degrees.

However if you rotated the hill with a simple coordinate transformation you would need to rotate gravity with it. For maximum horizontal range. 45circ is the ideal angle if your goal is to get maximum distance and you happen to be launching at ground level on a flat field with no atmosphere.

Also notice that the maximum. Answer 1 of 6. The sine function reaches its largest output value 1 with an input angle of 90 degrees so we can see that for the longest-range punts 2θ.

The maximum range will occur when the sum of the firing angle and the impact angle are 90 degrees so the firing angle must be reduced from 45 to achieve maximum range. The ideal angle to throw something is the angle that makes it do what you want. More sophisticated arguments for why the 45-degree launch angle yields the greatest range exist.

Proving the Maximum Range of a Projectile 45 Degrees. 2theta arcsin 1. Using the relation 2 sin L cos L sin 2L D V2 sin 2Lg Now sin 2L can take a maximum value of 1 and for this is to happen L 45 degrees.

At Cos 01 you have maximum horizontal velocity but no flight time. Share Improve this answer. Range a 2 2cosxsinxg a 2 sin2xg Now for maximum range sin2x should be maximum ie.

Therefore a projectile launched at. Sin 2theta 1. This is because sin 5cos 85 sin 85cos 5.

So in this case we have. The ideal theta is 45 degrees because this is the perfect compromise between flight time y-comp and horizontal speed x-comp. Your speed is now the resultant of a triangle which means the horizontalvertical components sidewaysforward speeds decrease.

θ 1 and we know that sin. Here the angle is changed by 5 degrees for each run. 1 sin2x1 sin2xsin90 2x90 x45 so for maximum range x 45.

The sine function reaches its largest output value 1 with an input angle of 90 degrees so we can see that for the longest-range punts 2θ 90 degrees and therefore θ 45 degrees. Unfortunately the 45 degree maximum range rule only works if gravity is directly downward so the equation would no longer be valid. Clearly from trigonometry we know that the maximum value of sin.

Why does the distance increase between you and the car youre following. Putting the value of t in acosxt. 90 0 1.

At a certain angle - 45 degrees if the starting point and end point are at the same level and air resistance can be ignored - and at a certain speed the range is. Ascending part making the angle at which the object hits the ground greater than the angle of the shot. This is becauseof gravity.

Answer 1 of 82. The maximum range occurs for a launch angle of 45. Now if were given the initial velocity the value of range will depend on theta observing this if we want to have a max Range we have to find the max value of sin 2theta but the max value of sine is always 1 therefore equating this to 1.

Therefore you will get a bowling effect rather than a tossing effect which has greater displacement. Theta 45 degrees. Halfway between those 45 degrees gets you the max range.
