Newton's law of motion

Question

solution

Answer 1

The acceleration is 0.6 m/s²
(A) is correct option
Explanation:

Given that,

Mass of man m₁= 40 kg

Mass of block m₂= 10 kg

Force = 30 N

We need to calculate the acceleration

Using formula of force

Where, M = mass of system

F = force

Put the value into the formula

Hence, The acceleration is 0.6 m/s²

As your app got fault

---

Here ans. Requires acceleration of whole system. Such that,
Acc. Of system= acc. Of boy + acc. Of block

---

Acc. Of system= 0.6+ 0.6
=1.2m/s^2
