Question

If a player catches a ball of mass 200 g moving with the velocity 40 ms -1, then he experiences a force of (time taken to catch the ball is 0.1 s ) (A) 20 N (B) 40 N (C) 50 N (D) 100 N

Tardigrade Admin · Accepted Answer

Mass of the ball m=200 g =0.2 kg Velocity of the ball v=40 ms -1 Time taken to complete the catch t=0.1 s From the Newton's second law of motion F =m a=(m v/t) =(0.2 × 40/0.1)=80 N

Q. If a player catches a ball of mass $200 g$ moving with the velocity $40 m s^{- 1}$ , then he experiences a force of (time taken to catch the ball is $0.1 s$ )

20 N

40 N

50 N

100 N

Mass of the ball $m = 200 g = 0.2 k g$
Velocity of the ball $v = 40 m s^{- 1}$
Time taken to complete the catch
$t = 0.1 s$
From the Newton's second law of motion
$F = ma = \frac{m v}{t}$
$= \frac{0.2 \times 40}{0.1} = 80 N$
