Question

A body of mass 4 kg is moving with a uniform velocity of 5 m/s. It is acted upon by a force of 12 N. What will be it's velocity after 1 s?​

Answer 1

$\huge\bold\pink{Answer:-}$

⏩ Here, m= 4 kg, F= 12 N

Therefore,

a= F/m= 12/4 = 3 m/s²

Now, u= 5 m/s, a= 3 m/s², t= 1 s

Therefore,

Final velocity, v= u + at = 5 + 3 × 1

= 8 m/s. Ans.

Answer 2

Answer:

8 m/s2

Explanation:

M = 4kg

F = 12N

u = 5 m/s

t = 1s

v = ?

now F = ma

a = F/m = 12/4 = 3 m/s2

now v = u + at

v= 5 + 3×1 = 8

final velocity = 8 m/s2
