Sophia pushes a shopping cart of mass 5 kilograms with a force of 12
newtons across the floor of a grocery store. The floor exerts a frictional force
of 7 newtons. What are the net force and acceleration of the cart?
net force 19 newtons
acceleration = 3.8 meters/second²
Onet force = 5 newtons
acceleration 1 meter/second²
=
Onet force = -5 newtons
acceleration = -1 meter/second²
Onet force = -5 newtons
acceleration
1 meter/second²
