A baseball batter hits a home run ball with a velocity of 132 ft/s at an angle of 26° above the horizontal
Problem 7:A baseball batter hits a home run ball with a velocity of 132 ft/s at an angle of 26° above the horizontal. A fielder who has a reach of 7 ft above the ground is backed up against the bleacher wall, which is 386 ft from home plate. The ball was 3 ft above the ground when hit. How high above the fielder's glove does the ball pass?

Doppler Effect:
5. Another Brick in the Wall 1604 You are in a car that is heading towards a brick wall at a speed of 32 m/s (72 mph). You know that the wall has a resonant frequency of 605 Hz, and that if a continuous sound wave at this frequency hits the wall, it will fall down.
