You slide a chair across a rough, horizontal surface. The chair's mass is 18.8 kg. The force you exert on the chair is 165 NN directed 26 degrees below the horizontal. While you slide the chair a distance of 4.70 mm , the chair's speed changes from 1.50 m/sm/s to 2.60 m/sm/s . Find the work done by friction on the chair.

initiated his siue Suppose you are pulling a 4.2-kg block across a rough, horizontal surface with a spring that has a spring constant of 100 N/m. What is the coefficient of kinetie friction between the surface and the block if the spring stretches by 3.2 em when you pull on the block at angle of 15° above the horizontal? Assume the block is moving with constant velocity

A 2.0 kg block starts from rest. It is pushed across a rough
horizontal surface by a force F (magnitude of F = 8.0 N) directed
at a 40° angle as shown. The block is found to accelerate along the
surface at 2.0 m/s2.
Prove that there is a frictional force acting on the block

A 5-kg sled is sliding on a horizontal rough surface with a speed of 18 m/s. The coefficier kinetic friction between the block and surface is 0.15. After travelling 25-m, it encounters as covered hill (where friction can be ignored) and slides uphill. The hill makes an angle of 38。 horizontal. (a) How much work is done against friction during the 25-m horizontal travel? the maximum elevation on the hill the block reaches? (c) How much work is done against...
