<h2>Impulse = Change in momentum = </h2><h2>Force x time = 32 kgms⁻¹</h2>
Explanation:
IMPULSE :
A large force acting for a short time to produce a finite change in momentum is called an impulsive force. It is defined as the product of the force and the time for which it acts and is equal to the total change in momentum.
we have F = 80 N
t = 0.4 s
Impulse = change in momentum = Force X time duration
= 80N x 0.4s = 32 kgms⁻¹
Yes it is possible, because the human skeleton will never disintegrate since it’s made of bone.
Answer:Food contains chemical potential energy. As our bodies digest it, the stored energy is converted into energy for us to move and grow.
