A block of mass 20 kg moves along a frictionless surface, and is in a collision course with a sphere of mass 10 kg tied to an inextensible rope of length 6.00m. If the block collides with the sphere with a velocity of 5.00 m/s, as shown in the figure, and the coefficient of restitution is e = 0.800, determine the following. Neglect friction and air resistance. € VB 5.00 m/s 0 r: 6.00m -T-- H t 3. To solve for the maximum height, H, which of the following concepts cannot be used? The kinetic energy of the sphere just after its collision with the block is equal to its potential energy at the maximum height, H. The kinetic energy of the sphere just after its collision with the block is equal to its kinetic energy at the maximum height, H. The velocity of the sphere at the maximum height is zero. The work done by gravity on the sphere will DECREASE the sphere's kinetic energy.

A 59.5 kg man standing on a frictionless surface pushes two large boxes in opposite directions as shown. Initially everything is a rest. If the left box has mass 41.5 kg and final speed 3.25 m/s, and the right box has mass 27.0 kg and final speed 2.00 m/s, what is the final velocity (magnitude and direction) of the man? Let the positive direction be to the right.

. The fisherman's mass is 79 kg, and the boat's is 126 kg. The fisherman and boat are initially at rest when the fisherman throws a package of mass m = 15 kg horizontally to the right with a speed of vi = 4.9 m/s. What is the velocity of the boat after the package is thrown? Neglect any resistance force from the water. (Give the magnitude in m/s, and select the correct direction from the options given.)  What is the direction of the boat?

A 40.0 kg child is standing on a 42 kg raft that is drifting with a velocity 0f 1.2 m/s [N]relative to the water. The child walks on the raft with a net velocity of 0.71 m/s [E]relative to the water. Fluid friction between the raft and the water is negligible.Determine the resulting velocity of the raft relative to the water. i and j vectors are notpermitted. dont forget the angle

A 140 g hockey puck is sliding across the frictionless surface of the ice at 2.32 m/s, and then a 12.6 N force is applied to it for 173 ms. At what angle (between Oo and 1800) from the initial velocity is the direction of the puck's final velocity if the force is applied at an angle of 1270 relative to the initial velocity?

A 90.0 kg fullback running 36.9° north of east with a speed of 5.00 m/s is tackled and held onto by an 60.4 kg opponent running north with a speed of 5.34 m/s. What is the magnitude of the velocity of the players immediately after the tackle?
