Two automobiles are 150 kilometers apart and traveling toward each other. One automobile is moving at 35 km/h and the other is moving at 40 km/h. In how many hours will they meet? A) 2.5 h B) 2.0 h C) 1.75 h D) 1.5 h F) 1.25 h

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?

4. An astronaut is said to have tried to get out of a traffic violation for running a red light ( 650. nm) by telling the judge that the light appeared green ( 540. nm) to her as she passed by in her high-powered transport. If this is true, how fast was the astronaut going?

50 40- 30 20 10- -10 10 20 30 10 You are a lifeguard and spot a drowning child 30 meters along the shore and 50 meters from the shore to the child. You run along the shore for a while and then jump into the water and swim from there directly to child. You can run at a rate of 3 meters per second and swim at a rate of 1.2 meters per second. How far along the shore should you run before jumping into the water in order to save the child? Round your answer to the hundredths decimal places.
