1. What force is needed to accelerate the stone of

mass 22.0 kg upward at 5.00 m/s2?

2. A rocket that weighs 8975 N on the earth is fired. The force of propulsion is 1.24 x 105 N.

a. Find the mass of the rocket.

b. The acceleration of the rocket.

c. The velocity of the rocket at the end of 10.0 s.

d. The displacement at the end of the above time frame. (10.0s)

3. A force of 13.0 N is necessary to keep the 3.5 kg wooden block moving along a table top at a uniform velocity. Calculate the co-efficient of friction. Draw a free body diagram.

4. A car moving on a high way has a mass of 1200kg. The coefficient of friction between the tire and the car is 0.2. What acceleration will a force of 1.25X 104 N produce on the car? Draw a free body diagram.
