Question

A can stand retarding force of 100N is applied to a body of mass 60kg moving initially with a speed of 32kg m/s. How long does the body take to come to halt. ​

Answer 1

Answer:

F = m*a

100 = 60* a

a = 100/60

= 5/3 m/s^2

v^2 = 2*a*s

32*32 = 2*5/3*t

Then required time is,

t = 32*32*3/10

= 307.2 sec
