Question: A projectile that is fired from a gun has an
A projectile that is fired from a gun has an initial velocity of 90.0 km/h at an angle of 60.0o above the horizontal. When the projectile is at the top of its trajectory, an internal explosion causes it to separate into two fragments of equal mass. One of the fragments falls straight downward as though it had been released from rest. How far from the gun does the other fragment land?
Answer to relevant QuestionsA moving shuffleboard puck has a glancing collision with a stationary puck of the same mass, as shown in Fig. 6.34. If friction is negligible, what are the speeds of the pucks after the collision? A 4.0-kg ball with a velocity of 4.0 m/s in the +x-direction collides head-on elastically with a stationary 2.0-kg ball. What are the velocities of the balls after the collision? In a pool game, a cue ball traveling at hits the stationary eight ball. The eight ball moves off with a velocity of 0.25 m/s at an angle of 37o relative to the cue ball’s initial direction. Assuming that the collision is ...In a noninjury chain-reaction accident on a foggy freeway, car 1 (mass of 2000 kg) moving at 15.0 m/s to the right elastically collides with car 2, initially at rest. The mass of car 2 is 1500 kg. In turn, car 2 then goes on ...How much momentum is acquired by a 75-kg sky-diver in free fall in 2.0 minutes after jumping from the plane?
