  1. Physics Equation Practice 1 1. What is the speed of a ball rolling down a hill that is 20m long if it takes 5 seconds? 2. What is the force of a 5 kg ball that is accelerating down a hill at 5ms-2? 3. How much force pressed down on a scale when a 125kg person steps on a scale? (use acceleration due to gravity) 4. How much would you weigh on the moon? (2.2lb = 1 kg and the moons gravitational pull is 1.624 ms-2) 5. How much would you weigh in outer space? (assume gravity = 0) 6. During a drift, a 2,200lb car moves sideways with 100N of force. What is the acceleration of the car? What is this in g’s? 7. What is the mass of an object that weighs 100N and is moving at 40m/s2? 8. What is the speed of a skateboarder that goes 1 km in 1 min?
