A cricket ball of mass 250 g collides with a bat with velocity 10 m/s and returns with same velocity within 0.01 seconds. The force acted on bat is
Options
(a) 25 N
(b) 50 N
(c) 250 N
(d) 500 N
Correct Answer:
500 N
Explanation:
Initial speed(u)=-10m/s
Final speed(v)= 10m/s
Mass (m)= 0.25kg
Time= 0.01 s
v=u+at
20= at
a= 2000 m/s²
F= ma
F= 0.25 x 2000
F= 25×20
F= 500 N
