Question

A body is projected vertically up the velocity 98m/s. after 2s if the acceleration due to gravity of earth dissappears, the velocity of the end of next 3s is

Answer 1

Answer:

velocity of the end of next 3s is 78.4m/s

Explanation:

after 2s

v=u+at

=98-9.8×2

=98-19.6

=78.4

since acceleration disappears

so, velocity will be constant

so,velocity of the end of next 3s is 78.4 m/s
