A lawn tennis ball of mass 300 g is thrown vertically upwards with a vertically of 10 m/s. The air cause a resistance of 10 m/s. The air caused a resistance of 0.5 N.
Determine
a. The net force on the ball as it moves up. (Take g=10m/s)
b. The acceleration of the ball
c. The maximum height reached by the ball.
