Question

the average force which is required to stop a moving ball with momentum of 25N in 0.04sec is

a) 625 N
b) 125 N
c) 50 N
d) 25 N
​

Answer 1

Answer:

4

Explanation:

here, force

first case : m= 25n, 0.04

• accleration, a= f / m = 0.04 / 25 = 1.6 sec

force= f= m ( v-u)/t

(625-125/ 50)

= 500 / 50

= 100/ 25

= 4 answer
