What is his new velocity? 4. An alien spaceship is 500 m above the ground and moving at a constant velocity of 150 m/s upwards. How high above the ground is the ship after 5 seconds? 5. A bicyclist is traveling at +25 m/s when he begins to decelerate at -4 m/s2. How fast is he traveling after 5 seconds? 6. A squirrel is 5.0 m away from you while moving at a constant velocity of 3 m/s away from you. How far away is the squirrel after 5 seconds? 7. A ball is dropped off a very tall canyon ledge. Gravity accelerates the ball at 9.8 m/s2. How fast is the ball traveling after 5 seconds? 8. During a race, a dragster is 200 m from the finish line when something goes wrong and it stops accelerating. It travels at a constant velocity of 45 m/s for 3 seconds to try to finish the race. How far from the finish line is the dragster after 3 seconds?
9. A dog is 60 m away while moving at a constant velocity of 10 m/s towards you. Where is the dog after 4 seconds?
