Question

A body is projected vertically upwards with velocity 98 m/s.after 3s if the accerelation due to gravity of earth disappears ,the velocity of the body at the end of next 3s.

Answer 1

After the projection no force is applied. Therefore: -g will work. so:
V=u +(-g)t
V=98×(-9.8)×3
V=98+(-29.4)
V=98-29.4
V=68.6m/s.
After the next 3 seconds no force is applied so velocity remains same.

Answer 2

Answer:

v=68.6 m/s
