- During a kick ball game, a ball is kicked with a velocity of 25m/s at an angle of 45 degrees above the horizontal. How long us the ball in the air and how far does the ball travel?A ball is launched from a 10.0 m building with an initial speed of 15.0 ?/?. If the ball’s speed when it reaches its maximum height is 1/3 its speed when it is at half its maximum height, determine ball’s launch angle and the ball’s angle at impact.

- A parent at a Little League game returns a foul ball by throwing it back onto the field. When the parent throws the ball back, she is standing and ends up releasing the ball from a point that is 2.50m above the ground. Your best guess is that she threw the ball upward at an angle of 60o with respect to the ground and it landed 13m away from her. What was the height of the ball's apex (as measured from the ground)?A paper ball is flicked at a 10 degree angle off of a table. The center of the ball is measured to be 1.018 meters from the ground at the time of the launch, and lands on the ground 1.600 meters away. What is the launch speed of the paper ball?A can rolls off a ledge. The ledge is 14.0 m above ground, and the ball has a speed of 8 m/s as it rolls off as shown in the sketch Sy-1ym Sx= Uset (a) how far from the edge of the ledge does the can hit the ground (b) a person 2 m tall stands 10 m from the ledge. Is that person hit? (c) what is the magnitude and angle w.r.t. the ground of the can's velocity just as it hits?
- To have anv hone of making nar on a hole. a golfer has to hit the next shot over some nearby trees and past a water hazard, whose far side is located-on level ground 100 m away. The ball is hit with an initial speed of 30 m/ at an angle of 45°, allowing it just to clear the trees. Does the ball get past the water hazard? 100 mA golfer is attempting to reach the elevated green by hitting his ball under a low-hanging branch in one tree A, but over the top of a second tree B. If the launch speed of the golf ball is vo = 115 mi/hr, what launch angle will put the first impact point of the ball closest to the pin? How far from the pin (distance d) is this impact point?

Neglect air resistance.Question 1) What is the maximum height, h, of the tennis ball? in mQuestione 2) What is the range, R, of the tennis ball? in m info given: what angle results in the greatest height=90 For this 90° angle, the horizontal component of velocity is zero, so the initial velocity is completely in the vertical direction, resulting in greatest height Kato tries substituting ty,max for t, 0 for yi, and h for yf, and gets h = vi2 sin2 ?i 2g When ?i = 90°, sin2 ?i is maximum, so h is maximum what angle results in the maximum horizontal range=45° I substituted 2vi sin ?i g into the expression for the horizontal component of velocity, (vi cos ?i)t, and got R = 2vi2 sin ?i cos ?i g when ?i = 45°, 2?i = 90°, and sin 90° = 1, which is its maximum value.
- A ball is thrown from the top of a 35 meter high tower at a velocity of 60 m/s and at an angle of 25o above the horizontal. How far from the base of the tower does the ball land? What is its velocity just as it strikes the ground?8. A projectile is fired from the ground, reaches a maximum height of 57.1 m and lands a distance of 52.9 m away from the launch point. What was the projectiles launch velocity? 55.0 m/s, 30.8 degrees above horizontal 34.4 m/s, 77.0 degrees above horizontal 33.5 m/s, 38.5 degrees above horizontal 7.8 m/s, 61.6 degrees above horizontalYou are attacking your enemy’s castle and prepare your catapult to launch a large stone at the castle wall. Asyour clan’s engineer, it is up to you to calculate the correct distance from the wall to fire your catapult. Youknow that the projectile will be launched from the catapult 8.2 m above the ground at a velocity of 40 m/s atan angle of 46◦ above the horizontal, and you want to hit the castle wall 3.0 m above the ground, where theprojectile will do the most damage. How far from the wall should your catapult be positioned?
