Body A of mass 3 kg and body B of mass 10 kg are dropped simultaneousl

1.	Body A of mass 3 kg and body B of mass 10 kg are dropped simultaneously from a height of 14.9 m . Calculate their momenta , potential energies and kinetic energies when they are 10 m above the ground
Answer» EXPLANATION: now, P.E(a)=mgh=3×9.8×10=29.4J P.E(B)=10×9.8×10=980J

Body A of mass 3 kg and body B of mass 10 kg are dropped simultaneously from a height of 14.9 m . Calculate their momenta , potential energies and kinetic energies when they are 10 m above the ground

Answer»

EXPLANATION:

now, P.E(a)=mgh=3×9.8×10=29.4J
