Practice for Quiz A rightward force of 302 N is applied to a 28.6kg crate. Determine the acceleration.

During a football workout, two linemen are pushing the coach on the sled. The combined mass of the sled and the coach is 300. kg. The sled accelerates at a rate of 0.580 m/s2. Determine the force applied to the sled by the linemen.

A 405 N rightward force is used to drag a large box across the floor with a constant velocity. The coefficient of friction between the box and the floor is 0.795. Determine the mass of the box.

A horizontal force of 99 N is required to set a 30.0 kg block in motion, and a 75 N force is required to keep it in motion at a constant speed once it is moving. What are the coefficients of static and kinectic friction?

The coefficient of static friction between a 19 kg object t and the rough surface is 0.62. The coefficient of kintic friction is 0.45. What is the MAXIMUM force that can be applied on the object before it starts moving?

A 100. kg object is at rest on a horizontal surface. The coefficient of static friction between the object and the surface is 0.60. How much applied force is required for the object to start moving?

A 200. kg object is at rest on a horizontal surface. The coefficient of kinetic friction between the object and the surface is 0.55. How much applied force is required to keep the object moving?
