6. A net force F causes mass mass m2 to accelerate at rate 2a. What is the ratio of mass mf to mass m2. A 0.60 kg softball initially at rest is hit with a bat. The ball is in contact with the bat for 0.20 second and leaves the bat with a speed of 25 m/s. What is the 7. magnitude of the average force exerted by the ball on the bat? A 1.2 x 10° kg car is accelerated uniformly from 10 m/s to 20 m/s in 5.0 seconds. What is the magnitude of the net force acting on the car during this nond interval? 8. elerate at a rate of 5.0
