Question

A force of 5n gives a mass m1 an acceleration of 10m/s2 and a mass m2 an acceleration of20m/s2.what is the acceleration when both the forces are tied together

Answer 1

When a force of 5N gives an acceleration of 10ms-² to a body 

Then,

Its mass = 5/10 kg = 0.5kg

So,

m₁ = 0.5kg

When a force of 5N gives an acceleration of 20ms⁻² to a body 

Then,

Its mass = 5/20 kg = 0.25kg

So,

m₂ =  0.25kg

When the two bodies r tied total mass of the system becomes = 0.75kg

So,

Acceleration of the system will b = force/mass = 5/0.75 = 6.67 ms⁻²
