Question

A force of 60 dynes acts upon a mass of 15𝑔 a) What acceleration is imparted to the body, b) What velocity will the body acquire in 8s? c) What distance will the body cover in this 8 𝑠?

Answer 1

60 dynes is 0.0006 N.

a) According to Newton's second law:

$$a=\frac Fm=0.04\text{ m/s}^2.$$

b) The velocity is

$$v=at=0.32\text{ m/s}.$$

c) The distance is

$$d=\frac{at^2}{2}=1.28\text{ m}.$$
