A 20 kg bike accelerates at 10 m/s2.  what was the force

• 25 Newtons
• 20 Newtons
• 200 Newtons
• 10 Newtons

A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s2. Determine the mass of the encyclopedia?

•  m = 3.0 kg
• m = 4.0 kg 
• m = 3.0 ml 
• m = 30.0 g

Determine the accelerations that result when a 12-N net force is applied to a 3-kg object. 

• 3 m/s
• 4 ft/s 
• 13 m/s
• 4 m/s 

If an object was accelerating at 10 m/s^2, and a force of 10 newtons was required to accelerate it, what was the object's mass?

• 1 kilogram
• 10 kilograms
• 2 kilograms
• 5 kilograms

• bottom
• both
• neither

What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Why is it harder for the boy in Image B to get down the hill?

• Motion
• Friction
• Work
• Displacement

If these boys are pulling with the same amount of force.  What will happen?

• The boy in blue will win.
• They will not move at all.
• The boy in red will win.
• Both will fall down.
