If we immerse an empty box of mass m = 3.8 kg in water, we see that it comes up with an acceleration of a = 2.9m/s2. How much sand do we need to fill the box to make it go down with the same acceleration?

A spherical bowling ball with mass m = 3.8 kg and radius R = 0.106 m is thrown down the lane with an initial speed of v = 8 m/s. The coefficient of kinetic friction between the sliding ball and the ground is p = 0.33. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down...

A box of mass ?=22.5 kg is pulled up a ramp that is inclined at an angle ?=17.0∘angle with respect to the horizontal. The coefficient of kinetic friction between the box and the ramp is ?k=0.305 , and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of ?=2.49 m/s2, calculate the tension ?T in the rope. Use ?=9.81 m/s2 for the acceleration due to gravity. FT=_____N
