Question

. An object of mass 8kg is moving with a constant velocity of 5m/sec. The force acting on it will be

40N
1.6N
0N
none of these
​

Answer 1

Answer:

0 N

Explanation:

We know that ,

According to Newton's Second Law of motion:

Force = Mass x Acceleration

Here acceleration = 0 $\frac{m}{s^{2} }$. [∵ Given that velocity is constant.]

Hence Force = 8 kg x 0$\frac{m}{s^{2} }$

                      = 0 N

Hope this helps you.
