Mike and Josh, two bicycles from towns d = 24 kilometers apart, set off in the same direction at the same time. Both Josh and Mike cycled at v, = 25 km/h. Instantly after they begin, a fly flies from Josh at the University of Michigan to Mike, and then immediately returns to Josh. Until the riders meet, the fly continues to fly back and forth between the cyclists.

You go watch your friend as she runs at a cross country meet. The first time she passes you, your friend runs by going due north at a speed of 4.40 m/s. You move to a different place on the course and twelve minutes after you saw her the first time, your friend runs past you again. This time she is traveling at a speed of 3.80 m/s in the direction 30.0◦ W of S. What is the direction of her average acceleration between those same two times?

The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 57 km/s. lo the crow's great surprisc, a Klingon ship is 150 km directly ahead, traveling in the same direction at a mere 21 km/s. Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 4 5s The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant Hint: Draw a position versus time graph showing the motions of both the Enterprise and the Klingon ship. Let æn - 0km be the location of the Interprise as it returns from warp drive I low do you show graphically the situation in which the collision is "barely avoided"? Once you decide what it looks like graphically, express that situation mathematically. Express your answer to two significant figures and include the appropriate units. a = μA Value m s² Review |…

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 vo = 33.7 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 t₁ = 0.710 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 x = 123 m from the base of the cliff. How high above the beach was the ball when it was thrown? initial height: X 1₁ m
Two students perform an experiment with a train and a ball. Michelles rides on a fltcar pulled at 7.85 m/s by a train on a straight, horizontal track; Gary stands at rest on the ground near the tracks. When michelle throws the ball with an initial angle of 57° above horizontal, from her point of view, Gary sees the ball rise straight up and back down above a fixed point on the ground. A. Did michelle throw the ball toward the front of the train or toward the rear of the train? Explain b. What was the initial speed of Michelle’s throw? c. What was the initial speed of the ball as seen by Gary?
The black market sold Einstein a gun that is able to launch clumps of cookie dough. By accident einstein launches two clumps of cookie dough back to back vertically into the air. Launch speed was equivalent to 40m/s and time between launches = 5.5s. The cookie doughs collide and clump into 1 massive clump in the air and come back and clogg the gun. At what speed does the big clump enter the gun assuming both clumps were in mass. %3D
