a man and his elephat play basketball and work together to dunk the ball. the mans body undergoes projectile motion. the image is at an angle but the man is launched from a height of H = 1.8 m and travels a horizontal distance of 9.4 m. relative to the horizontal the man launched at an angle of theta = 62 degrees.

a) whats the speed (vi) of the man at the moment he was launched from the platform?

b) whats the time of flight from launch to landing?

c) whats the max. hieght the man reaches above the ground?

d) how long after the launch did the man the highest point?

e) with what speed does the man impact the ground?

f) whats the total mechanical energy (kinetic + gravitational potential engergy) of the man the moment hes launched. assume the man has a mass of 70 kg.

g) whats the total mechanical energy of the man at exactly 0.89 s after he is launched

A streamlined and compact projectile is launched from flat ground on a valley toward a distant hillside at an Army testing ground in Nevada. The projectile’s initial speed is vi = 150. m/s as it leaves the cannon. The initial angle of launch θi of the projectile is unknown. The projectile makes impact high on the distant hill a time t = 3.00 s after its departure. From GPS sensors we know that the site of impact is a straight-line...

In order to launch a projectile over a wall, you need to obtain a tangential velocity of 30 m/s at a launching angle of 45 degrees from horizontal. Your projectile is attached to the arm of a catapult of length 3.5 m which is initially oriented horizontally. When the arm is released, the catapult will provide a constant angular acceleration until ejecting the projectile at the 45 degree angle. The projectile has a mass of 70 kg. What angular acceleration...
