Question

A force of body 0.6 N acting on a body increase velocity from 5 m/s to 6m/s in 2 sec.calculate its mass

Answer 1

Explanation:

Given :

• Force (F) = 0.6 N
• Initial velocity (u) = 5 m/s
• Final velocity (v) = 6 m/s
• Time (t) = 2 sec

To find:

• Mass (m) of the body.

Solution :

${\boxed{\sf{F=m\times\dfrac{(v-u)}{t}}}}$

Now put values .

$\implies \sf \: 0.6 = m \times \dfrac{(6 - 5)}{2} \\ \\ \implies \sf \: 0.6 = m \times \dfrac{1}{2} \\ \\ \implies \sf \: 1.2 = m \\ \\ \implies \sf \: m \: = 1.2$

Therefore, mass of the body is 1.2 kg.
