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.

Answers

joseph
a. F = mg
=.30 X 10
=3N
Net force = 3 – 0.5
=2.5 N
b. F = ma
2.5 = 0.3a
a=25/3m/s^2
c. V^2 = u^2 – 2as but v =0
S =u^2/2a
=100/(2x10)
=5m
