    2.  A girl on the roller skates accelerates at a rate of 2m/sec/sec with a force of 100N.
                What is her mass?
 

    3.  What force was applied to a 682 kg car to move it out of traffic at a rate of 2m/sec/sec?
 

    4.  An originally stationary car with a mass of 1500 kg reaches a velocity of 15 m/sec, 5 seconds after starting.
                What is the car's acceleration?
 
 
 

                How much force was required to reach this acceleration?
 
 
 

    5.  A 7000 kg plane is launched from an aircraft carrier in 2 seconds by a force of 250,000N
