1. A man hits a golf ball (0.24 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 aisle. The cart is full of groceries and has a mass of 18kg. The cart accelerates at a rate of 3m/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 25 grams (= ? kg) and accelerates at a rate of 5 m/s2. How much force (in Newton's) 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, a larger friend who has a mass of 70kg 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 9kg, and gravity accelerates it at the usual 9.8 m/s2. How much force does the earth apply to the hammer?
7. A car whose mass is 1000kg is travelling at a constant speed of 10 m/s. Neglecting any friction, how much force will the engine have to supply to keep going at the same speed? (tricky question, think INERTIA, look at the units)
