During WWI, the Germans had a gun called Big Bertha that was used to shell Paris. The initial velocity of the shell was 1700 m/s at an angle of 55° above the horizontal. Assume it returns to the same height as released. Ignore air resistance. 1. Find the total time in the air for the shell. 2. How far away did the shell hit? 3. Find the shell's velocity at the apex. 4. Find the horizontal and vertical velocity components just when the shell strikes the ground.

1. According to legend, George Washington threw a silver dollar across the Potomac River, which is about 1600 m (1 mile) wide. For this problem, assume projectile motion and that the quarter was thrown at an angle of 45° and it landed at the same height it was thrown. A. How fast would he have had to throw the silver dollar to make it across the Potomac? B. Assess your answer from part a). Does this seem like a plausible feat?

A baseball is hit with a speed of 30.0 m/s at an angle of 49.0 . It lands on the flat roof of a 10.0 m -tall nearby building.

Part A A shot-putter throws the "shot" (mass = 7.3 kg) with an initial speed of 14.1 m/s at a 43.0 ° angle to the horizontal. Calculate the horizontal distance traveled by the shot if it leaves the athlete's hand at a height of 2.15 m above the ground.
