1
A force of N is applied to the handle of a lawnmower. The handle makes an angle of º with respect to the horizontal. The lawnmower has a mass of 20.0 kg. What is the horizontal acceleration in m/s/s of the mower if the friction is N?

2
A crate with a mass of kg is pulled by a rope across a smooth level floor. Friction is negligible. When a force of N is applied to the rope the crate accelerates at m/s/s. What angle (in degrees) does the rope make with the floor?

3
A kg crate is pulled across a level floor with a force of N. The force acts at an angle of 30º up from the horizontal. The kinetic coefficient of friction is . What is the acceleration (in m/s/s) of the crate?

4
A boy on a toboggan have a combined mass of kg. Friction is negligible. If he slides down a slope with an angle of º, what is his acceleration in m/s/s?

5
A boy on a toboggan have a combined mass of kg. The coefficient of friction is . If he slides down a slope with an angle of º, what is his acceleration in m/s/s?
