Question

A stone of mass 20g is released from a catapult whose rubber has been stretched through 4cm. If the force constant of the rubber is 200N. calculate the velocity at which the stone leaves the catapult

Answer 1

Explanation:

A stone of mass 20g is rele.ase from a ca.tapult whose rub.ber has been stre.tched through 4cm, if the force constant of the rub.ber is 200N/M . calc.ulate the velocity with which the stone leaves the cata.pult. F = 200N/m ×0.04m = 8 N. W = F×d = 8×0.04 = 0.32 J.
