Match the term on the left with the definition on the right. slope the steepness of a line instantaneous speed the speed of an object at an instant in time acceleration the change in speed in a given time; speeding up, slowing down or changing direction speed the distance an object travels in a certain time velocity speed in a given direction You and your family are driving along in a 65 mph zone. A highway patrolman comes up behind you and turns his lights on. You pull over and he says that you were going 77 mph. What speed does he give you? average speed instantaneous speed acceleration none of these A cheetah is able to run 40 meters in 1.5 seconds. What is the cheetah's average speed? 60 m 0.04 m 26.7 m I don't have enough information to calculate this. Usain Bolt's cousin ran a race at a speed of 9 m for 11.1 seconds. What was the distance of the race? 400 m 200 m 1000 m 100 m A train moving at a speed of 20 m slows down to 10 m in 10 seconds. What is the train's acceleration? (hint: negative acceleration) 1 m 200 m -1m None of the these. The train is not accelerating. A bicyclist speeds up from 6 m to 12 m in 3 seconds. What is the cyclist's acceleration? -2 m 2 m 18 m 72 m
