1. How much net force
is needed to accelerate a 15kg mass at 2.8 m/s

^{2}?
2. Delon’s car is dead. He is pushing
it to the east out of the parking lot with a force of 250N. carter, being a
good friend, comes to help and also pushes east with a force of 75N. If Delon’s
car has a mass of 750kg, what is the car’s acceleration?

3. Hunter is pulling on his little red
wagon to the west with a force of 125N. Luke doesn’t want him to take the wagon
so he is pulling in the opposite direction with a force of 75N. If the wagon
has a mass of 15kg, what is the wagon’s acceleration?

4. A planes engine is pushing it north
with a force of 1250N. The wind is blowing to the east with a force of 125N. If
the plane is a 775kg mass, what is the

**of its acceleration?***magnitude*
5. A 50.0kg box is being pulled by two
teams of people. Team Bonzo is pulling on the box with a force of 324N @ 40.0˚
N of E. Team Kong is pulling on the box with a force of 856N @ 20.0˚ W of N.
What is the resultant acceleration of the box? (There are

**calculations needed to get to the proper answer!)***NINE*
