1.) A 10 kg block at a height of 7 m above the ground slides down an incline to the ground. Assume there is no friction between the block and the incline, and assume the coefficient of friction between the block and the ground is μ = 0.12. Once the block is on the ground, what is the magnitude (in N) of the normal force on the block?

2.) A net force of 10 N moves a 3 kg object initially at rest a horizontal distance of 5 m directly in the direction the force is acting.

C: What is the velocity in m/s of the object immediately when the force has moved it 5 m?

3.) A 10 kg block at a height of 7 m above the ground slides down an incline to the ground. Assume there is no friction between the block and the incline, and assume the coefficient of friction between the block and the ground is μ = 0.12.

G: How far in meters does the block slide on the ground before it comes to rest?
