A student witnesses a flash of lightning and then t = 1.5 s later the student hears the associated clap of thunder. Sound travels at 343 m/s in the air. What distance from the student is the lightning strike, in meters? Light travels at 3.0 × 108 m/s in the air. How long, t1, in seconds did it take the light to reach the student's eyes after the lightning strike?

A furlong is a distance of 220 yards. A fortnight is a time period of 2 weeks. A race horse is running at a speed of 2.3 yards per second. What is his speed in furlongs per fortnight?.5

Bob has just finished climbing a sheer cliff above a level beach and wants to figure out how high he climbed. All he has to use is a baseball, a stopwatch, and a friend on the ground below with a long measuring tape. Bob is a pitcher and knows that the fastest he can throw the ball is about ?0=34.1 m/s.v0=34.1 m/s. Bob starts the stopwatch as he throws the ball, with no way to measure the ball's initial trajectory, and watches carefully. The ball rises and then falls, and after ?1=0.910 st1=0.910 s the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball hit the ground ?=123 mx=123 m from the base of the cliff. How high above the beach was the ball when it was thrown?

as a person drives along the highway, they decided to measure the distance between each light post.the person driving at a steady 60.0 mph and it takes , on average 4.00s to go from one light post to the next light post
