Question

a spring scale is used to exert a net force of 2.7 N on a cart.if the cart’s mass is 0.64 kg,what is the cart’s acceleration

Answer 1

Solution. Using Newton’s second law, we write

$$F=ma$$

where F=2.7N is force; m=0.64kg is mass; a is acceleration. Therefore

$$a=\frac{F}{m}=\frac{2.7}{0.64}\approx 4.22\frac{m}{s^2}$$

Answer.

$$a=4.22\frac{m}{s^2}$$
