Answer to Question #84708 in Mechanics | Relativity for evie

Question

Trolley with a mass of 15 kg is accelerated at 3 m/s2. What force is needed to do this?

Answer 1

We can find the force that needed to accelerate the trolley from the Newton's Second Law of Motion:

$$F = ma = 15 \thinspace kg \cdot 3 \thinspace \frac{m}{s^2} = 45 \thinspace N.$$

Answer:

$$F = 45 \thinspace N$$
