Question

12 A body of mass 10 kg is moving with a constant
velocity of 10 ms When a constant force acts for 4 s on
it it moves with a velocity 2 ms in the opposite
direction. The acceleration produced in it is​

Answer 1

Answer:

Hey

initial velocity u= 10m/s

final velocity v=2m/s

time T= 4 sec

we know, F=m(v-u)/t

therefore Force=10*(2-10)/4

= -20N

we know,

F=ma

-20=10*a

a=-10m/s^2
