Question

A body falls freely under gravity the final velocity of a body after 15 seconds will be

Answer 1

given that,

A body falls freely under gravity

therefore, initial velocity is zero

we know that,

v = u + at

therefore, v = 0 + gt

therefore, v = 9.8 × 15

therefore, v= 147 m/ s

hope it is useful for you

Answer 2

Given that,

A body falls freely under gravity therefore, initial velocity is zero

we know that,

v = u + at

So, v = 0 + gt

= 9.8 × 15

Finally, v = 147 m/s
