How much time does it take a person to walk 12 km at a velocity of 6.5 km/h? What is the velocity of a rocket that goes 700 km north in 25 seconds? Acceleration You ride your bike around the at a constant speed of 11 km/hr. Did you accelerate? Explain. A patriot missile is moving at 240 km/h east and travels to its maximum of 450 km/h east in 3 minutes. What is the acceleration? Force You push a friend sitting on a swing, she has a mass of 50kg and accelerates at a rate of 4m/s2. Find the force you Exerted How much more force would it take to push a friend who has a mass of 70kg to accelerate at the same rate of 4m/s2 Work It took 50 joules to push a chair 5 meters across the floor. With what force was the chair pushed? A force of 100 newtons was necessary to lift a rock. A total of 150 joules of work was done. How far was the rock lifted? Gravity The Tower of Terror in Disneyland drops its “victims” 13 stories (3 m/story). What would be the potential energy of a elevator car of 5 people who have a total mass of 116 kg? The value of gravitational pull on the moon is 1.6 m/s/s. What is the weight of a 75 kg astronaut on the moon?
