Fig. shows an estimated force-time graph for a base ball struck by a bat. From this curve, determine
(i) impulse delivered to the ball
(ii) force exerted on the ball
(iii) the maximum force on the ball.

Explanation

(i) Impulse = Area under F-t curve
= Area of `DeltaABC=(1)/(2)xxOPxxAC=(1)/(2)xx18000xx(2.5-1)`
`=1.35xx10^(4)kg ms^(-1)`
(ii) Average force`=("Impulse")/("Time") =(1.35xx10^(4))/((2.5-1))=9000N`
