Question

A body of mass M, at rest explodes into three
masses, two of which having mass M/4flown off in
perpendicular directions with velocity 3 ms and
4 ms respectively. The third piece will be flown off
with a velocity
(1) 5 ms
(2) ms
(3) 2 ms-
(4) 3 ms​

Answer 1

The acceleration of a body is 3 ms⁻². This means that the velocity changes in every two seconds by a) 2 ms⁻¹b) 3 ms⁻¹c) 6 ms⁻¹d) 9 ms⁻¹
