Question

The displacement of a body is given by s= 1/2gt2, where g is acceleration due to gravity .the velocity of the body at any time t is
(1) gt3/6. (2) gt2/2
(3) gt. (4) gt/2

Answer 1

The displacement of a body is given by s= 1/2gt2, where g is acceleration due to gravity .the velocity of the body at any time t is gt.

Explanation:

This is because we know acceleration is g and time is t so that by using the formula v=u+at and putting the given values in it we get v = gt where u=0.

Answer 2

The Answer is gt.

This is because the method v = u + at

where u is 0
