Answer to Question #263205 in Physics for Nick

Question

Find the force necessary to keep the toy car in equilibrium. The mass of the toy is 5kg and the inclination of the plane is 30°. Friction is neglected.

Answer 1

Given:

$\theta=30^{\circ}$

$m=5\:\rm kg$

The force required to keep the toy car in equilibrium

$$F=mg\sin\theta=5.0*9.8*\sin 30^{\circ}=25\:\rm N$$
