Question

A body of mass 5kg is moving with a velocity of 10 m/s . It is acted upon by a force of 20 N. Find velocity of the object after 1 sec.

Answer 1

$\huge\mathbb\purple{Here\:is \:the \:answer}$

________________________________

M = 5 kg

u = 10 m/s

F = 20 N

t = 1 sec

v = ?

acceleration = $\frac{Force}{mass}$

a = $\frac{20}{5}$

a = 4 m/s

V = u + at

V = 10+ 4 *1

V = 10+4

$\huge\boxed{v = 14 m/s}$
