A(n) donkey carries a(n) infinity stone 82.4 m horizontally across a flat desert plain at some constant velocity. If the infinity stone has a mass of 33.0 kg, what is the work done on the infinity stone by the donkey?

A 97 N force is applied at an angle of 19° above the horizontal to a 3.00 kg box. The box moves a distance of 6.6 meters horizontally. Friction is negligible. Find the work done by the 97 N force.

A 5.00 kg object is pushed against a spring of spring constant 499 N/m, compressing it a distance of 0.62 m. The object is released and travels 0.10 m across carpeting with a coefficient of kinetic friction of 0.49. It next travels up a frictionless ramp. How high does it go up the ramp? m

How far did you travel in the time it takes you to stop? mm
What is the distance between you and the tractor when you finally come to a stop? mm

Curling is a winter sport in which players slide an 18.0 kg stone across flat, level ice with the stones stopping as close as possible to a target (the “house”) some distance away. A curler releases her stone with an initial velocity of 5 m/s, and the stone stops at the house 24.0 s later.Determine the acceleration of the stone.
a=a= ms2ms2
Determine how far the stone traveled.
Δx=Δx= mm
Determine the frictional force that brings the stone to a stop.
f=f= NN
Determine the coefficient of kinetic friction between the stone and the ice.
