Question

Given that the mass of an object m= 5Kg moving in a straight line with initial velocity u= 25 m/s and final velocity becomes 10 m/s in 5 sec . What is the amount of force exerted ? *

1 point

(c) F = 15 N

(d) F = - 20 N

(b) F = 20 N

(a) F= -15 N​

Answer 1

Answer:

ans= -15N

Explanation:

given

mass=5kg

initial velocity(u) = 25m/s

final velocity (v) = 10m/s

time(t)=5 secs

acceleration= v-u/t

=10-25/5=-15/5

=-3m/s^2

f=ma

=5*-3 = -15N
