Question

A body of mass 5 kg is moving with a velocity of 10 m/s. It is acted upon by a force 20 N in
the direction of motion. Whạt will be its velocity after 1 second?
[Ans. 14 m/s]​

Answer 1

Answer:

Mass = 5kg, Force applied = 20N

So, acceleration produced = Force/mass = 4 m/s^2

Now, initial velocity (u) = 10 m/s, acceleration (a) = 4m/s^2, time (t) = 1 s

So, final velocity (v) = u + at = 10 + 4(1) = 14 m/s.

Hope you understand.
