Friction Practice Problems Name
1. A 55,0 kg box is pulled by a 325 N Force at an angle of 28.0 degrees above
- the horizontal. The force of kinetic friction is 25.0 N.
Draw a free-body(force) diagram for the box and label the applied
force, the applied force in the x and y direction, the force of gravity, the
force of kinetic friction and the normal force.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
