Question

An object of mass 17.0 kg subjected to a non-zero net force moves with an acceleration of 2.2 m/s^2.(a) Determine the net force (in N) acting on it. (Enter the magnitude only.)N(b) What acceleration (in m/s2) would a 34.0-kg object have if the same net force is applied to it?m/s?

Answer 1

m= 17 kg

a = 2.2 m/s^2

F = m x a

F= 17 kg x 2.2 m/s^2 = 37.4 N (a)

(b)

m= 34 kg

F= 37.4 N

F= m x a

a = F/ m

a = 37.4 N / 34kg = 1.1 m/s^2 (b)
