Question

Assume you push a 20kg child in a little red wagon with a force of 100N. However, the dirt and rocks below the wheels create a frictional force of 25 N. What is the acceleration on the wagon and child?

Answer 1

3.25 m/s²

Step-by-step explanation:

from second newten law

∑F = ma

100-25 = 20 * a

a = 75/20

=3.25
