One strategy in a snowball fight is to throwa snowball at a high angle over level ground.While your opponent is watching this firstsnowball, you throw a second snowball at alow angle and time it to arrive at the sametime as the first.Assume both snowballs are thrown withthe same initial speed 25.6 m/s. The firstsnowball is thrown at an angle of 52° abovethe horizontal. At what angle should youthrow the second snowball to make it hit thesame point as the first? Note the starting andending heights are the same. The accelerationof gravity is 9.8 m/s

Here both the snowballs are thrown with the same initial speed 25.6m/s. The angle thrown for the…

An airplane takes off and flies upward at an angle of 21° with a constant speed of 262 m/s. While the plane is flying upward, a piece of the engine falls off when the plane reaches a height of 860 m. a) How long does it take the piece of the engine to reach the ground? Give your answer in seconds. b) What is the horizontal distance covered by the piece of the engine before it lands? Give your answer in meters.
Several people stand on a bridge over a river. The bridge is not level, so the people are all different heights above the river. Each person throws a stone to the river. a) The first person is 26.8 m above the river and throws her stone with a speed of 16.6 m/s at an angle of 6 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below). How long does it take her stone to hit the water, in seconds? b) The second person is 19.0 m above the river and throws his stone with a speed of 17.1 m/s at an angle of -21.4 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below). What is the range of his stone, in meters? c)The third person is 9.1 m above the river and throws their stone with a speed of 6.5 m/s at an angle of 9.3 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below). What is the speed of this stone (in m/s) just before it strikes the river?
A rocket is fired at a speed of 86.0 m/s from ground level, at an angle of 31.0° above the horizontal. The rocket is fired toward an 7.92- Im high wall, which is located 16.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall? Number i Units

Dock diving is great form of athletic competition for dogs of all shapes and sizes. Sheba, the American Pit Bull Terrier, runs and jumps off the dock with an initial speed of 9.02 m/s at an angle of 25.0° with respect to the surface of the water. Sheba begins at a height of 0.840 m above the surface of the water. What is her total time of flight up until the instant before she hits the water? Express your answer in seconds.
1. Vivian is practicing her shooting accuracy with her slingshot by trying to shoot rubber balls into a bucket on the ground. For one particular shot for which the ball lands in the bucket, she fired her slingshot horizontally with an initial speed of 56.0 m/s at a height of 170 cm above the ground. (a) How far away is Vivian standing from the bucket? (b) What are the magnitude and direction of the ball's velocity when it lands in the bucket? Note: Please be mindful of significant figures. Also, you can assume that when the balls land in the bucket, they are on the ground.
a boy fires an arrow from a height of 1.80 m at an angle of 15° above the horizontal towards a target standing 15.00 m in front of him. He misses the target completely, and the arrow goes flying past the target and hits the ground 21.1 m behind the target. Determine the initial velocity of the arrow in m/s.
Snowballs are thrown with a speed of 19 m/s from a roof 7.0 m above the ground. Snowball A is thrown horizontally; snowball B is thrown in a direction 35° above the horizontal. Find the direction of motion (that is, the angle of the velocity vector) of each of the two snowballs just before they land.
Irina, standing on the edge of a cliff, throws a stone at a 40-degree angle above the horizontal with an initial speed of 10.0 m/s. The instant before the stone hits the ground below, it is traveling at a speed of 63 m/s. If Irina were to throw the other rock at a 40-degree angle below the horizontal from the cliff instead, with the same initial speed of 10.0 m/s, what is the magnitude of the velocity of the stone just before it hits the ground?
