In a Mythbusters stunt, a basketball is launched from the top of a 100.0 m tall building at an initial velocity of 20.0 m/s [15.0° above the horizontal]. The ball flies through the air and passes through a small window on a second building which is located 80.0 m away. Assume that air resistance can be ignored. What was the height of the window in the second building? What was the velocity of the ball as it passed through the window?

- A golf ball is hit off the ground with a speed of 34.0 m/s at a 56.0° angle with the horizontal. If the a. How high (in meters) does the ball rise? Answer: [Select] m b. If the ball lands on the ground at the same height that it was hit, how much time does the ball spend in the air? Answer: [ Select ] C. How many meters away does the ball land? Answer: [ Select ] mA projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?A skateboarder decides to try to jump from the top of a set of stairs and land at the level bottom. She leaves the top of the stairs with a horizontal velocity of 15.0 m/s. If the top of the stairs is 2.0 m high, what will her airtime be?
- answer with solution working out please!During a recent winter storm, bales of hay had to be dropped from an airplane to a herd of cattle below. Assume the airplane flew horizontally at an altitude of 172 m with a constant velocity of 58.0 m/s and dropped one bale of hay every 4.0 seconds. It is reasonable to assume that air resistance will be negligible for this situation. About how far apart from each other will the bales land on the ground? Answer: m (rounded to the nearest whole number)You threw a tennis ball from a balcony 4.1 m above the ground upward at 45 degrees above horizontal with an initial speed of 4.0 m/s. What was the magnitude of the total final velocity?
