KINETIC ENERGY 1. A 1 kg rock is at a height of 100 meters. What is the rock's gravitational potential energy at 100 meters high? 2. A 60-kg person walks from the ground to the roof of a 74.8 m tall building. How much gravitational potential energy does she have at the top of the building? 3. A 70-kg man is walking at a speed of 2.0 m/s. What is his kinetic energy (energy is measured in Joules)? 4. A 1400-kg car is moving at a speed of 25 m/s. How much kinetic energy does the car have? WORK 1. An object is horizontally dragged across the surface by a 100 N force acting parallel to the surface. Find out the amount of work done by the force in moving the object through a distance of 8m. 2. A 10 kg object experiences a horizontal force which causes it to accelerate at 5, moving it a distance of 20 m, horizontally. How much work is done by the force? KINEMATICS 1. The slowest animal ever discovered is a crab found in the Red Sea that travels an average speed of 5.7. How long will it take this crab to travel 1. 2. A tortoise and a hare are in a roadrace to defend the honor of their breed. The tortoise crawls the entire 1000 meters at a speed of 0.2. The rabbit runs the first 200 meters at 2, stops to take a nap for 1.3 hours, and awakens to finish the last 800 meters with an average speed of 3. Who wins the race and by how much time?
