When a cricketer lowers his hands while catching a ball, the force on his hands:
ADecreases
BIncreases
CStays the same
DBecomes zero
Answer & Solution
Correct answer: A. Decreases
1. The change in momentum of the ball is fixed by its mass and velocity at impact.
2. Impulse equals force times time: F·t = Δp.
3. Lowering the hands while catching increases the duration of impact (t).
4. For a fixed Δp, increasing t reduces the average force F.
5. So the force felt by the hands decreases when the cricketer lowers his hands.
