A 85.1 kg toy rocket is sent flying straight up into the air with an acceleration of 5.00 m/s². After 4.30 s it explodes and breaks apart into two pieces. The heavier piece has a mass of 64.0 kg. If the lighter piece is able to reach a maximum height of 180. m above the ground, what is the speed of the heavier piece of the toy rocket just after the explosion?

Question 1
A 85.1 kg toy rocket is sent flying straight up into the air with an acceleration of 5.00 m/s². After 4.30 s it explodes and breaks apart into two pieces. The heavier piece has a mass of 64.0 kg. If the lighter
piece is able to reach a maximum height of 180. m above the ground, what is the speed of the heavier piece of the toy rocket just after the explosion?
Question 2
A basketball explodes into three separate pieces. Two pieces of equal mass shoot off at 26.3 m/s, one travelling to the south and one to the west, perpendicular to each other. The third piece has a mass 3
times the size of one of the other pieces. What is the speed of the third piece?
