Question

a force acting on a body of mass 20kg changes its velocity from 20m/s to 40m/s in​

Answer 1

Answer:

PLS TELL THE TIME ALSO THEN THE ANSWER WILL COME

Answer 2

GIVEN :

mass = 20 kg

initial velocity (u) = 20m/s

final velocity (v) = 40 m/s

TO FIND :

force

SOLUTION :

force = mass × acceleration

acceleration = velocity/ time = 40 -20 / 1 = 20m/s²

force = 20 × 20 = 40 N
