Mechanics in action 1. What is the velocity of a snowball that travels 35 m in 5 s? 2. A car goes from 0 m/s to 60 m/s in 12 s. What is the cars acceleration? 3. A 25 kg rock is accelerated at 2 m/s². What force is being applied to the rock? 4. A portable x-ray machine as a mass of 477 kg. What is its weight (in Newtons) on Earth? On the moon? 5. A truck with the mass of 1530 kg is traveling at a velocity of 40 m/s. What is the trucks momentum? 6. Find the work done in lifting a kettle bell weighing 45 N to a height of 2 m. 7. A radiographer lifts a 1.0 kg grid from the floor to the top of a 1.6 m table with an acceleration of 2.5 m/s². What is the power exerted if it takes 1.0 s? 8. A patient with a mass of 110 kg is being pushed in a wheelchair a distance of 200 m in 2 min. Find the patient's kinetic energy. 9. A radiographer holds a 0.7 kg film 1.75 m above the ground. What is its potential energy?
