We start with some review problems A crate of mass 20.0 kg rests on a level surface, with a coefficient of kinetic friction 0.219. You push on the crate with an applied force of 297 N. What is the magnitude of the crate s acceleration as it slides?     12.70 m/s^2     14.85 m/s^2     6.35 m/s^2     20.79 m/s^2

upward acceleration of he is pulled upward at a constant velocity? Ans: 999 N; Question 14. To hoist himself into a tree, a 72.0-kg man ties one end of a nylon rope around his waist and throws the other end over a branch of the tree. He then pulls downward on the free end of the rope with a force of 367 N. Neglect any friction between the rope and the branch, and determine the man's upward acceleration. Use g -9.80 m/s². Ans: 0.394 m/s² ung whose weight is 519 N is being pulled up vertically by a rope from the that and without

Two ropes are attached to a 40 kg object. The rope with a 50 N force points along a direction 37 degrees from the positive x-axis, and the other rope with a 50 N force points along a direction 140 degrees. What is the acceleration of the object in m/s/s? O 8.91 O 8.58 O 12.43 O 40.73 O 7.57

The kinetic friction force between a 58.0-kg object and a horizontal surface is 41.0 N. If the initial speed of the object is 26.0 m/s, and friction is the only force acting on the object, what distance will it slide before coming to a stop? m (round to the nearest whole number) Answer:
