Question

a force of 5N Produces an acceleration if 8m s2 in mass m1 and an acceleration of 24ms2 In mass m2 .what acceleration would it give if both the masses are tied up together

Answer 1

6m/s2 is the acceleration

Answer 2

Using the formulae : F = ma where F is the force, m the mass and a the acceleration we can get m₁ and m₂.

Since F is same for the two scenarios we use 5N to get the two masses.

m = F/a

m₁ = 5/8 = 0.625Kg

m₂ = 5/24 = 0.2083Kg

When the two masses are joined and Same force applied we get a as:

m₁ + m₂ = 0.2083 + 0.625 = 0.8333Kg

a = F/m

5 / 0.8333 = 6.0002m/s²
