Question

a force of 20n, acting on a mass of m1 produces an acceleration of 4m/s^2 the same force when applied to a mass m2 give an acceleration of 0.5m/s^2 what acceleration would the same force produce when both masses are tied together

Answer 1

●●m'= F/a = 20/4 = 5kg   ●●m'' = 20/0.5 = 40 kg   ●●m = (m' + m'') = 45kg   ●●a(final) = 20/45 = 4/9 = 0.44 m/s^2  @skb
