Question

A body of mass 5 kg is moving with a uniform velocity 10m/s it is acted upon by a force 20n what will be velocity after 1s

Answer 1

mass = 5kg

acceleration = f/m

force = 20n

a = 20/5 = 4m/s^2

acceleration = v-u/t

v = ?

u = 10m/s

t = 1s

a = v-u/t

4 = v-10/1

4+10 = v

velocity = 14m/s

Answer 2

Hey mate!!

Here's your answer!!

$Given$

Mass = 5kg
Initial Velocity = 10m/s
Force = 20 N
Time = 1s
We know that;
$F = ma$

Where F is force, m is mass and a is acceleration.
By this formula, we get;
Acceleration = 4m/s^2

By the first equation of motion;
$v = u + at$

Putting the values in it;
$v = 10 + (4 \times 1) \\ = 10 + 4 \\ = 14$

Therefore, 14 m/s is the answer.

Hope it helps!!
