Question

A spring is used to launch a ball vertically in to the air. the spring has a spring constant of 200 N/m and is compressed by 5 cm.A ball of mass 10 g is placed just above the spring.Calculate [A]the energy stored in the spring [B] assuming the spring transfers all of its energy to the ball,the velocity of the ball just as it launches [C] the height reached by the ball assuming all the Ek is converted in to GPE

Answer 1

Answer:2.55 m

Explanation:

Elastic energy = gravitational energy

½ kx² = mgh

h = kx² / (2mg)

h = (200 N/m) (0.05 m)² / (2 × 0.010 kg × 9.8 m/s²)

h = 2.55 m
