Question

The acceleration of two objects are 5m/s2 and 20m/s2. If mass of both the object would be combined and a force of 50N would be applied on them, what will be their acceleration?

Answer 1

Answer:

a = 4ms⁻²

Explanation:

Given informations:-

F = 50 N

a₁ = 5ms⁻²

a₂ = 20ms⁻²

F=m*a

For 1st object:

50 N = m₁ * 5ms⁻²

m₁=50 / 5 = 10Kg.

For 2nd object:

50 N = m₂ * 20ms⁻²

m₂ = 50 / 20 = 2.5 Kg.

Total mass (M)= m₁+m₂ = 10 + 2.5 = 12.5 Kg.

Acceleration after combination:

F = M*a

a = F / M

a = 50 / 12.5 = 4ms⁻².

I hope my answer really helped you.
