Question

A boy with a mass of 30.0 kg is sliding down a snow covered hillside at an angle of 25.00 degrees to the horizontal. Find the boy's acceleration if the coefficient of kinetic friction is 0.17.

A box with a mass 26.50 kg if being pulled by three forces : F1 46.25 N , F2 10.00 N [164.50]^o and F3 9.06 N [229.85]^o. Determine the acceleration of the box. (Note direction is not required, quote your answer to 2 decimal place)

A person with a mass of 78 kg is riding in an elevator which is accelerating at 1.80 m/s². What is the person’s apparent weight?

A force of 12 N acting in a direction [E30^o S] is equivalent to which of the following pairs of forces acting simultaneously?

A 1.5-kg cart is pulled with a force of 7.3 N at an angle of 40° above the horizontal. If a kinetic friction force of 3.2 N acts against the motion, the cart’s acceleration along the horizontal surface will be

A 24-N horizontal force is applied to a 40-N block initially at rest on a rough horizontal surface. If the coefficients of friction are μs = 0.5 and μk = 0.4, the magnitude of the frictional force on the block is:
