A cricket ball of mass 50 g and velocity 50 cm/s is stopped in 0.5 s. What is the force applied?
Show Hint
Use \( F = \frac{mv}{t} \) when object is brought to rest; watch units carefully.

- 0.07 N
- 0.05 N
- 5 N
- 7 N

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Convert to SI units:
Mass = 0.05 kg, Velocity = 0.5 m/s, Time = 0.5 s
Force \( F = \frac{mv}{t} = \frac{0.05 \times 0.5}{0.5} = 0.05\ \text{N} \)

- Two blocks A and B of masses 2 kg and 4 kg respectively are kept on a rough horizontal surface. If same force of 20 N is applied on each block, then the ratio of the accelerations of the blocks A and B is (Coefficient of kinetic friction between the surface and the blocks is 0.3 and acceleration due to gravity = \(10 \operatorname{ms}^{-2}\))
