Question

A 6.9 kg object undergoes an acceleration of 3.0 m/s2.(a) What is the magnitude of the resultant force acting on it?_____ N(b) If this same force is applied to a 4.1 kg object, what acceleration is produced?_____ m/s2

Answer 1

a)

Given:

m = 6.9 kg

a = 3 m/s^2

Apply:

F = ma

F = 6.9 x 3 = 20.7 N

b)

F = ma

a = F /m

a = 20.7 / 4.1 = 5.05 m/s^2

Answers:

a) 20.7 N

b) 5.05 m/s^2
