A 0.2-kg bullet is fired into a 1.8-kg pendulum bob as shown in the diagram to the right. The bullet gets stuck inside the pendulum bob after striking it with an unknown initial horizontal velocity. If the pendulum bob is observed to be moving at 10 m/s immediately after the collision, what was the speed of the bullet just before it collided with the pendulum bob? h = ? Vi = ? 100 m/s 90 m/s 75 m/s 50 m/s​

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

truck y has a greater velocity than truck x.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
