One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching this first snowball, you throw a second snowball at a low angle and time it to arrive at the same time as the first. Assume both snowballs are thrown with the same initial speed 10.6 m/s. The first snowball is thrown at an angle of 56◦ above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? Note the starting and ending heights are the same. The acceleration of gravity is 9.8 m/s 2

One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching this first snowball, you throw a second snowball at a low angle and time it to arrive at the same time as the first. Assume both snowballs are thrown with the same initial speed 20.5 m/s. The first snowball is thrown at an angle of 68◦ above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? The acceleration of gravity is 9.8 m/s 2 . Answer in units of ◦ .
Skeet Shooting is an Olympic sport for rifle marksmen. A skeet is a clay target. A lady marksman goes out to practice and sets her skeet launcher at a position 25 meters north and 40 meters west from where she intends to stand. When she yells “Pull!”, a skeet is launched due East at an angle of 37 degrees above the ground with an initial speed, vo. The marksman only fires due north. Two seconds after she yells “Pull!”, the bullet from her gun hits the clay skeet in the air. At what height did the clay skeet shatter? Neglect air friction effects. {Use sin(37o) = 3/5; cos(37o) = 4/5; and g = 10 m/s2 }

A blue person throws an object with an initial velocity of 25.0 m/s at an angle of 37.0°. A green person stands 15.0 meters in front of the blue person and throws an object straight up. Assume that both objects are thrown from the same initial elevation. a)If the green person throws their object with an initial speed of 20.0 m/s, at what time should they throw it such that it strikes the other object while it is traveling upward? Measure this time relative to when the blue person throws theirobject? b)If both people throw their objects at the same time, with what initial speedmust the green person throw their object such that theycollide? Answers: a) ~0.267 s b) ~15.0 m/s

A baseball is hit into the air at an initial speed of v0 = 25.6 m/s at angle ? = 60o above the horizontal. At the same time the ball is hit, an outfielder starts running towards the batter and catches the ball at the same level it was hit. ?he outfielder is initially L = 91.7 m from home plate. 1) Find the average speed of the outfielder. Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 18 m/s at an angle 38 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground. What is the maximum height the ball goes above the ground? #What is the distance between the two girls? After catching the ball, Sarah throws it back to Julie. The ball leaves Sarah's hand a distance 1.5 meters above the ground, and is moving with a speed of 17 m/s when it reaches a maximum height of 9 m above the ground. # What is the speed of the ball when it leaves Sarah's hand? #How high above the…
You hit a ball with an initial velocity of 25 m/s at an angle of 34° above the horizontal. You are at an initial height of 24 m above the point where the ball lands. What is the magnitude of the velocity of the ball just before it lands? Use a kinematic approach.
