Presentation transcript:

You push a large crate with a force of 125 N. It accelerates at a rate of 5 m/s/s. What is the mass of the crate?

With what force must you hit a 5-kg baseball to get an acceleration 175 m/s/s?

You and your bicycle have a mass of 75-kg. If your pedals put a forward force of 190 N, and friction pushes you backwards with a force of 20 N. Air resistance also pushes you backwards with 10 N. a.) Draw a Free-Body Diagram to find Net Force. b.) Calculate acceleration

A car has mass of 1000-kg. If your engine put a forward force of 2500 N, and friction pushes you backwards with a force of 300 N. Air resistance also pushes you backwards with 150 N. a.) Draw a Free-Body Diagram to find Net Force. b.) Calculate acceleration

You are using a rope to lift a 15-kg bucket out of a well. a.) What net force do you need to get an acceleration of 1.2 m/s/s? b.) The weight of the bucket is a downward force of 150 N. Draw a Free-Body Diagram to find the force on the rope.

You pull an anvil forward with a force of 200 N. One of you friends pulls it backwards at 100 N. a.) What is the magnitude and direction of the net force. b.) If it accelerates at 0.5 m/s/s. What is the mass of the anvil?

What is the mass of an object that accelerates at 2 m/s/s when acted on by 10 N of force?

You are jumping out of an airplane. Gravity pulls you down with a force of 980 N. You deploy a parachute that pulls you up with a force of 900 N. a.) Draw a free body diagram to find the magnitude & direction of the net force b.) If your mass is 100 kg, what is your acceleration?

You push a 1500-kg crate forward with 20 N of force. There is 15 N of friction pushing the crate backwards. a.) Draw a free body diagram to find the magnitude & direction of the net force b.) What is the acceleration?

A marble is being pulled by gravity down a ramp with 4.9 N of force. There is 1.9 N of friction. a.) Draw a free body diagram to find the magnitude & direction of the net force b.) What is the acceleration if the marble’s mass is 0.5 kg?

a.) Find the net force (magnitude & direction) b.) If the block accelerates at 5 m/s/s, calculate the mass. 10 N 20 N 50 N

A helicopter’s propeller’s exert an upward force of 14,000 N. The weight of the helicopter pulls it down with a force of 12,000 N. a.) Draw a free body diagram. Find the net force (magnitude & direction) b.) If the mass is 1224 kg, find the acceleration.

A motorcycle has a forward force of 100 N. The air drag pushes it backwards by 10 N, and friction pushes it backwards by 5 N. a.) Draw a free body diagram. Find the net force (magnitude & direction) b.) If the mass is 15 kg, find the acceleration.
