Please include solutions so I can understand them better. Thank you!

1. A 15.5-ke block is pushed to the right across a level surface at a P constant velocity by a force P that is inclined 35 to the horizontal. as shown. The coefficient of kinetic friction between the block and the surface is 0.325. What is the magnitude of the 15.5 kg force P? 2. A 2.25-kg ball with an initial velocity of 25.71 - 2.35j meters per second strikes a vertical wall. The wall exerts a constant force of - 875i newions on the ball. The ball's final velocity after impact is -21.4i - 2.35j meters per second. (a) Find the ball's change in momentum. (b) How long is the ball in contact with the wall? 3. A 3.15-kg steel ball traveling at 25.0/3350 meters per second 335 collides with and embeds itself in a 10.5-kg block of clay traveling at 4.20/80 meters per second. Find the velocity of the combined mass immediately after impact. 80 4. A 50.0-ke homogeneous beam supports a mass of 15.0 kilograms. as shown. The center of gravity of the beam is at the midpoint of the beam. Find the magnitude of the tension. T. in the rope. T 37 15.0 kg -5.00 m 5. A 50.0-kilogram block hangs on a rope which passes over a massless. frictionless pulley, as shown. It is connected to a 40.0- kilogram block which rests on a frictionless inclined plane. 50.0 kg (a) Find the acceleration of the blocks. 40.0 kg (b) Find the magnitude of the tension in the rope. 60 Multiple Choice 6.
