1.) Force F pulls a box having 4-kg mass from point A to B. If the friction constant between surface and the box is 0.3; find the work done by F and work done by resultant force.

2.) A mass is dropped from a height of 4-m onto a spring with a constant of 120 N/m. If the spring compresses by a maximum amount of 1.25-m, what is the mass of the object?

3.) A 2,100-kg car starts from rest at the top of a 5-m long driveway that is inclined at 20.0 degrees with the horizontal. If an average friction of 4,000-N impedes the motion, find the speed of the car at the bottom of the driveway.
