A man hits a golf ball (0.2 kg) which accelerates at a rate of 20 m/s2. What amount of force acted on the ball? 2. You give a shopping cart a shove down the isle. The cart is full of groceries and has a mass of 18 kg. The cart accelerates at a rate of 3 m/s2. How much force did you exert on the cart? 3. The wind pushes a paper cup along the sand at a beach. The cup has a mass of 0.025 kg and accelerates at a rate of 5 m/s2. How much force is the wind exerting on the cup? 4. You push a friend sitting on a swing. She has a mass of 50 kg and accelerates at a rate of 4 m/s2. Find the force you exerted. 5. How much force would it take to push another, larger friend who has a mass of 70 kg to accelerate at the same rate of 4 m/s2? 6. A worker drops his hammer off the roof of a house. The hammer has a mass of 9 kg, and gravity accelerates it at the usual 9.8 m/s2. How much force does the earth apply to the hammer? CALCULATING WEIGHT WORKSHEET (Newtons 2nd Law) Calculate weight (force due to gravity) in the following problems by using the equation: weight = mass x free-fall acceleration w = m g g (on Earth) = 9.8 m/s2 Be sure to (1) ALWAYS write the equation (2)plug in the numbers and units, (3) give the answer with the correct units. 7. A physical science test book has a mass of 2.2 kg What is the weight on the Earth? 8. What is the weight on Mars (g = 3.7 m/s2) 9. If the textbook weighs 19.6 newtons on Venus, What is the strength of gravity on Venus? 10. Of all the planets in our solar system, Jupiter has the greatest gravitational strength. If a 0.5 kg pair of running shoes would weigh 11.55 newtons on Jupiter, what is the strength of gravity there? 11. If he same pair of shoes weighs 0.3 newtons on Pluto, what is the strength of gravity on Pluto? 12. What does the pair of shoes weigh on Earth?
