Student Worksheet for Newton’s Laws After you’ve worked through the sample problems in the videos, you can work out the problems below to practice

doing this yourself. Answers are given on the last page.

Kinematic Equations:

xf – xi = vit + ½ at2 OR d = vi + ½ at2

vf2 = vi

2 + 2a(xf – xi) OR vf2 = vi

2 + 2ad

xf – xi = ½ (vf + vi)t OR d= ½ (vf + vi)t

vf = vi + at (Where: t=time, d=displacement, x=position, v=velocity, a=acceleration, i=initial, f= final)

Practice Problems:

1. A man and his son are in a car on the way to school and are travelling at 25 kph. However, the son has

forgotten to fasten his safety harness. A deer runs across the path and the man hits the brakes, stopping the

speeder and missing the deer. What speed will the son hit the windshield of the car? (Assume the car stops

before the son does)



2. An engine on a space shuttle can be accelerated from rest to 1000 kph in 1.5 seconds. What is the

acceleration of the engine?

3. For problem #2 above, what is the force required if the engine has a mass of 300 kg?



4. As a training exercise, a personal trainer is making a 100kg woman pull a 34 kg sled across a frozen lake.

The woman must pull on the 13m long rope that is attached to the sled. If both the woman and the sled

begin at rest and the woman pulls with a force of 7.3N towards him, what are the accelerations of both the

woman and the sled?

5. What is the weight in Newtons (N) and mass in kg of an 8 pound baby T-rex?



6. A small 220 gram bolt from an aircraft is 3.4 m deep in the Atlantic Ocean and is falling with constant a

terminal speed of 43 m/s. What force does the ocean exert on the bolt?

7. A spacechip is under attack and all crew must evacuate. If the captain of the ship weighs 241 lbs. and slides

down a pole to the escape pod with a downward acceleration of 13 ft/s2, what upward force does the pole

exert on the captain?



8. A spy must parachute onto a beach to save the world from a nuclear detonation. However, the beach has a

laser defense system that will shoot anything that is accelerating faster than 1.5 m/s2. If the spy has a mass

of 65 kg and his parachute has a mass of 7 kg, what upward force on the parachute is necessary to ensure

the spy is not shot down?

9. How can a burglar lower his 115 pound gold brick into his underground safe using a rope that has a

breaking strength of 72 pounds?



10. An F-14 Tomcat weighs 30 tons with all ordinance attached and fully fueled. The pilot knows that his plane

needs a speed of 325 ft/s to take off. The engine for the Tomcat only produces 27,000 pounds of thrust and

the runway for the aircraft carrier is only 320 feet long. What force must the catapult of the aircraft carrier

apply to the pilot’s airplane so that he can takeoff safely? (Assume both the engine and the catapult exert a

constant force over the 325 ft runway)
