Aboy pushes on a wagon so that it accelerates at a rate of 0.50 m/s2. the wagon has a mass of 24 kg. what is the magnitude of the boy's pushing force? (ignore frictional effects.) 12 n, 12 kg, 48 n, or 48 kg

To find the magnitude of the boy's applied force, use newton's second law (where the force is the mass times the acceleration)

F = ?
m = 24 kg
a = 0.50 m/s^2

F = ma
F = (24 kg) (0.50 m/s^2)
F = 12 N

therefore the magnitude of the boy's pushing force is 12 N

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

Iwould say a is accurate
