A 600-g ball A is moving with a velocity of magnitude 5 m/s when it is hit by a 1-kg ball B as shown which has a velocity of magnitude 3 m/s. Knowing that the coefficient of restitution is 0.7 and assuming no friction, determine the following:

You throw a baseball directly upward at time t = 0 at an initial speed of 12.3 m/s. what is the maximum height the ball reaches above where it leaves your hand? at what times does the ball pass through half the maximum height? ignore air resistance and take g = 9.80 m/s2.

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

Looking at this barometer, is the air pressure high or low? what type of weather would you expect? high, bad low, bad high, good low, good
