Question
A lightweight drone (1.00 kg) is launched at 800 m high and moves upward at a constant velocity (while
ignoring the effects of gravity only on the drone). The balloon, when measured at a horizontal distance from
you, is about 1600 m away from you. At the moment when the drone moves, you shoot a bullet (weight =180
g) with an initial velocity of 1009 m/s at a fixed angle α, where sin α=3/5 and cos α= 4/5. (g = 9.8 m/s2) (10
pts each)
a. How long does it take for the bullet to collide with the drone?
b. At what height will the bullet hit it?
c. What is the upward velocity of the drone?
d. Provided that the collision is inelastic, calculate the speed after the collision.
e. Calculate the height the two objects taken from the impact up to the maximum height before it starts
falling to the ground.
