y 10 ms from height 9.5 m. It penetrates
he sand by 50 cm and stop. The change in
mechanical energy will be (g = 10 ms)​

Answer 1

Answer:

A steel ball of mass 5 g is thrown downward with velocity 10ms−1 from height 19.5m. It penetrates sand by 50 cm. The change in mechanical energy will be g=10ms−2
