1. A stone is thrown from a hill at an angle of 60° with the horizontal on an initial velocity of 30 m/s. After hitting the level ground at the base of the hilI, the stone has covered a horizontal distance of 150 m. How high is the hill? 2. A plane is flying horizontally 350 kph at an altitude of 420 m. At this instant, a bomb is released. How far horizontally from this point will the bomb hit the ground? v = 350 kph = 97.22 m/5 y = 420 m 3. A ball is thrown from a tower 30 m. High above the ground with a velocity of 300 m/s directed at 20° from the horizontal. How long will the ball hit the ground? Vo = 300 m/s 20° y = 30 m 4. A balloon is ascending at the rate of 10 kph and is being carried horizontally by a wind at 20 kph. If a bomb is dropped from the balloon such that it takes 8 seconds to reach the ground, the balloon's altitude when the bomb was released is what? Pach of the 5.556 ms

1. A stone is thrown from a hill at an angle of 60° with the horizontal on an initial velocity of 30 m/s. After hitting the level ground at the base of the hill, the stone has covered a horizontal distance of 150 m. How high is the hill? 2. A plane is flying horizontally 350 kph at an altitude of 420 m. At this instant, a bomb is released. How far horizontally from this point will the bomb hit the ground? Ve = 350 kph = 97.22 m/s y = 420 m 3. A ball is thrown from a tower 30 m. High above the ground with a velocity of 300 m/s directed at 20° from the horizontal. How long will the ball hit the ground? Vo = 300 m/s e = 20° y = 30 m 4. A balloon is ascending at the rate of 10 kph and is being carried horizontally by a wind at 20 kph. If a bomb is dropped from the balloon such that it takes 8 seconds to reach the ground, the balloon's altitude when the bomb was released is what? Path of he Eioos 556 ms
