Question

4. O/N 18/P11/08
A ball of mass m is thrown vertically into the air. When the ball has speed v, the air resistance acting on the ball
is F.
What is the magnitude of the acceleration of the ball when its speed is v as it rises and as it falls?​

Answer 1

Answer:option B

Explanation:a=F/m

Net acc=g-a when it goes against gravity

Net acc=g-f/m

While falling down

Net acc=g+f/m
