One strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then, while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 25.0 m/s. The first is thrown at an angle of 70.0° with respect to the horizontal. (a) At what angle should the second snowball be thrown to arrive at the same point as the first? (b) How many seconds later should the second snowball be thrown after the first in order for both to arrive at the same time?

One strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume that both snowballs are thrown with a speed of 30.0 m/s. The first is thrown at an angle of 65.0° with respect to the horizontal. (a) At what angle should the second snowball be thrown to arrive at the same point as the first? _____° (b) How many seconds later should the second snowball be thrown after the first in order for both to arrive at the same time?
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 }

During a heated game of bocce ball, Ursula is attempting to knock the pallino (the small, white target ball) away from where her opponent's balls lie on the ground. She can do this by throwing her ball so that it lands directly on top of the pallino, which is x = 17 m horizontally downcourt from where she throws. If she releases the ball y = 0.90 m above the ground at an angle of 0 = 23° above the horizontal, then how much time will the ball spend airborne before hitting the pallino? Both balls may be treated as point particles in this problem.
Two friends are playing golf. The first friend hits a golf ball on level ground with an initial speed of 39.0 m/s at an angle of 33.0° above the horizontal. (a) Assuming that the ball lands at the same height from which it was hit, how far away from the golfer, in meters, does it land? Ignore air resistance. m (b) The second friend hits his golf ball with the same initial speed as the first, but the initial velocity of the ball makes an angle with horizontal that is greater than 45.0°. The second ball, however, travels the same horizontal distance as the first, and it too lands at the same height from which it was hit. What was the angle in degrees above horizontal of the initial velocity of this second golf ball? Ignore air resistance. ° above the horizontal
In a basketball game, the point guard A intends to throw a pass to the shooting guard B, who is breaking toward the basket at a constant speed of 12 ft/sec. If the shooting guard is to catch the ball at a height of 6.9 ft at C while in full stride to execute a layup, determine the speed vo and launch angle with which the point guard should throw the ball. A Answers: Vo = VO 0 0 = 6.0' 44.34 i 38.31 38¹ 12 ft/sec B ft/sec O 20' 6.9¹ V
Problem 4: A person shoots a gun at a target that is 65 m away. The center of the target is at the same height as the gun. The person aims the gun upward at an angle so that the bullet hits the center of the target. The bullet leaves the gun at a velocity of 210 m/s. What is the angle of the gun in degrees from the positive x-axis? Numeric : A numeric value is expected and not an expression.
A placekicker kicks a football at an angle of 20.0 degrees and the initial speed of the ball is 15 m/s. Ignore air resistance. Determine the range R of the projectile.
A basketball hoop has a height of 3.05 m and the distance between the hoop and the free throw line is 4.57 m. If a person who is 1.90 m tall shoots the ball from the free throw line at an angle of 54.0° with respect to the horizontal, at what speed should the ball leave her hands?
In a live fire exercise, an Army artillery team fires an artillery shell from a howitzer. The barrel of the howitzer makes a 54.0° angle above horizontal, and the speed of the shell upon exiting the barrel is 350 m/s. The shell hits a target on the side of a mountain 35.5 s after firing. Assuming the point where the shell exits the barrel to be the origin, and assuming as usual that the x-axis is horizontal and the y-axis is vertical, find the x and y coordinates, in meters, of the target. x = y = m m
