13) A 4.00 kg box is pushed 2.00 m across a level surface by an applied force of 32.0 N, 0°. The box then slides an additional 3.00 m before coming to a rest. (a) Determine the amount of friction. (b) Determine the box’s maximum speed over the 5.00 m distance traveled.

How much work would be needed to raise the payload from the surface of the moon (i. e., x = r) to an altitude of 5r miles above the surface of the moon (i. e., x = 6r)?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
