Question

When a 18N force acts on a 3kg mass for a second, the change in velocity is (in m/s) ________.

(a) 36 (b) 6 (c) 2 (d) 18​

Answer 1

Answer:

According to Newtown 2nd law of motion,

F = ma

Here

F = 18N

m = 3 kg

So by putting values,

we get a = 6 m/s²

So change in velocity is acceleration.

So answer = 6
