Projectile Motion - Rocket Clears Wall - General LaunchAngle
A rocket is fired at an initial speed v0 = 165.0 m/s from groundlevel, at an angle θ = 50° above the horizontal.
A wall is located at d = 67.0 m. Its heigh is h = 47.0 m. Ignoreair resistance.
The magnitude of the gravitational acceleration is 9.8 m/s2.
Choose the RIGHT as positive x-direction. Choose UPWARD aspsotitive y-direction
Find v0x, the x component of the initial velocity (in m/s) .Keep 2 decimal places.
Find v0y, the y component of the initial velocity (in m/s) .Keep 2 decimal places.
You will calculate the time at which the rocket flies over thewall.
To find this time, should you use the horizontal (x) motion orthe vertial (y) motion?
(a) At what time (in seconds) (after being fired) does therocket fly over the wall? Keep 4 decimal places.
Note: when the rocket flies over the wall, in general, theheight of the rocket is not equal to the maximum height.
(b) What is the rocket's height (in meters) when it flies overthe wall? Keep 3 decimal places.
(c) By how much (in meters) does the rocket clear the top of thewall? Keep 3 decimal places.
(d) What is the rocket's maximum height (in meters) above theground? Keep 2 decimal places.
