In the drawing, the weight of the block on the table is 405. N and that of the hanging block is 191. N. Ignore friction, the mass of the rope, and the mass of the pulley. Find the acceleration of the two block system in m/s2.

A student is skateboarding down a ramp that is 5.38 m long and inclined at 19.4 degrees with respect to the horizontal. The initial speed of the skateboarder at the top of the ramp 2.52 m/s. Neglect friction and find the speed at the bottom of the ramp in m/s.

thank you so much

When a 51.7 gram tennis ball is served, it accelerates from rest to a speed of 41.2 m/s. The impact with the racket gives the ball a constant acceleration over a distance of 49.5 cm. What is the magnitude of the net force acting on the ball in newtons?
