net force= m*a
92-70-19=23*a
solve for a
Suppose two children push horizontally, but in exactly opposite directions, on a third child in a wagon. The first child exerts a force of 70.0 N, the second exerts a force of 92.0 N, friction is 19.0 N, and the mass of the third child plus wagon is 23.0 kg.
(b)
Calculate the acceleration (in m/s2). (Enter the magnitude.)
(c)
What would the acceleration be (in m/s2) if friction were 22.0 N? (Enter the magnitude.)
