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

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

Answer 2

Answer - 14 m/s

Explanation:

Mass (m) → 5 kg

Initial Velocity (u) → 10 m/s

Force (f) = 20 N

To find - Final velocity (v)

Firstly we will find acceleration (a)

→ F = m.a

→ 20 = 5 × a

•°• Acceleration = 4 m/s²

Now

v = u + at

v = 10 + 4 × 1

v = 14 m/s
