Question

A small wooden block with mass 0.775 kg is suspended from the
lower end of a light cord that is 1.74 m long. The block is initially

horizontal velocity vo. The bullet strikes the block and becomes
embedded in it. After the collision the combined object swings on
the end of the cord. When the block has risen a vertical height of
0.700 m, the tension in the cord is 4.90 N.

A 2.70-kg ball is shot into a 0.425-kg box that is at rest on a frictionless, horizontal table (see figure below); after the collision, the ball is embedded in the box. The box is attached to a 0.30-m rope that is attached to the table on the other end. The ball's initial velocity is perpendicular to the rope as shown.

A boy cruising across a smooth, level sidewalk is approaching a pipe guard-rail. It seems like a good idea for him to jump over the rail and let the skateboard pass under the rail. The mass of the boy is 38.8 kg, the mass of the skateboard is 2.43 kg, the initial cruising speed is +5.22 m/s, and the instant after leaving contact with the board, the boy's velocity relative to the sidewalk is 5.33 m/s, 9.27° above the horizontal. If we ignore the force of friction between the skateboard and the sidewalk, determine the skateboard's velocity relative to the sidewalk at the instant the boy leaves the board. m/s
