A pitcher and catcher are separated by 10m and are playing catch with a baseball. The catcher begins walking toward the pitcher the instant he threw the ball. The ball bounced off the catcher’s glove back to the pitcher, then bounced off the pitcher back to the catcher’s mitt, and so on until the catcher reached the pitcher and the ball was trapped between the two. If the catcher walked toward the pitcher at a rate of 1 m/sec and the ball traveled at a speed of 14 m/sec, what was the total distance the ball traveled back and forth before being trapped?​

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
