A packing crate with mass 80.0 kg is at rest on a horizontal, frictionless surface. At t = 0 a net horizontal force in the +x-direction is applied to the crate. The force has a constant value of 80.0 N for 12.0 s and then decreases linearly with time so it becomes zero after an additional 6.00 s.   What is the final speed of the crate, 18.0 s after the force was first applied?

The surface of a pool table is h=0.710 m from the floor. The winner of a competition wants to know if he has broken the world speed record for the break shot of 32 mph (about 14.3 m/s). A. If the winner’s ball landed d=4.95 m from the table’s edge, calculate the speed of his break shot v0. Assume friction is negligible. B. At what speed v1 did his pool ball hit the ground? Image is attached below. Please show all work.

An applied force of 42.3 N directed at an angle of -17.7 degrees with respect to the +x direction acts on a 2.95 kg mass that is initially at rest while on a horizontal surface. In moving a distance of 2.67 m in the +x direction, the object changes its kinetic energy by 31.5 J. What is the coefficient of kinetic friction

An empty sled of mass 25 kg slides down a muiddy hill with a constant speed of 2.4 m/s The slope of the hill is inclined at an angle of 15 degrees with the horizontal. a. Calculate the frictional force on the sled as it slides down the slope b.Calculate the coefficient of friction between the sled and the muddy surface of the slope c. The sled reaches the bottom of the slope and continues of horizontal ground. Assume the same coefficient of friction. In terms of velocity and acceleration, describe the motion of the sled as it travels on horizontal ground.

A hockey puck with mass 0.166 kg is pushed across the ice with a constant force of 0.89 N. The coefficient of kinetic friction between the puck and the ice is 0.22. After a distance of 2.6 m, what is the puck's speed in m/s?

A truck with mass m has a brake failure while going down an icy mountain road of constant downward slope angle alfa (see figure). Initially the truck is moving downhill at speed v0. After sliding downhill a distance L with negligible friction, the truck driver steers the runaway vehicle onto a runaway truck ramp of constant upward slope angle beta. The truck ramp has a soft sand surface for which the coefficient of rolling friction is f. After an unknown distance D along the ramp the truck comes to a halt. The acceleration of gravity is g. What is the total work Wf done by the friction force on the runway ramp?

You are in an elevator that is initially at rest. At t=0, it heads downward and speeds up as a function of time.
