Your friend claims he can throw a baseball straight up with a speed of 80 mi/h. You do not
believe him, so you design an experiment that will enable you to calculate the speed of a thrown
ball. You attach a 0.5-kg block to a vertical spring. The block hangs a distance of 0.05 m below
the relaxed position. Your friend stands directly beneath the hanging block and throws the
baseball straight up. He releases the ball at a distance of 2.4 m below the hanging block. You
design the experiment so that the ball sticks to the block after the collision. You observe that the
block-baseball combination rises a distance of 0.18 m after the collision.
 Do you believe that your friend can throw a baseball with a speed of 80 mi/h?

A plane flying horizontally at an altitude of 5 mi and a speed of 470 mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 7 mi away from the station. For full credit I expect to see a well-labeled picture. Show all work. Round your final answer to the nearest whole number. Do not round intermediate values. Include units of measure in your answer.

The question: A teacher is trying to figure out how fast he can throw a Baseball, but doesn't have a radar gun. He does have the following: - Baseball - Soft styrofoam Block ( In which the ball could become embedded into during a collision) - A level tabletop - A metre stick - A balance scale. The teacher also has determined the coefficient of friction between the block and table. NOTE: The kinetic coefficient of friction is determined while...

Assume that your friend claims that he can run 20 km in less than an hour and a professional sports team will recruit him after graduation based on this outcome so he does not worry about his GPA at the university. You would like to test this claim and take a random sample of 34 runs this year and find that he averaged 58.2 minutes. Assume that the standard deviation of his runs is 8.5 minutes and it is normally...

- Your friend claims he has a fair coin; that is, the probability of flipping heads or tails is equal to 0.5. You believe the coin is weighted. Suppose a coin toss turns up 15 heads out of 20 trials. At α = 0.05, can we conclude that the coin is fair (i.e., the probability of flipping heads is 0.5)? You may use the traditional method or P-value method.
