A catapult on a cliff launches a large round rock towards a ship on the ocean below. The rock leaves the catapult from a height H of 34.0 m above sea level, directed at an angle 0 above the horizontal with an unknown speed vo. The projectile remains in flight for 6.00 seconds and travels a horizontal distance D of 179.0 m. Assuming that air friction can be neglected, calculate the value of the angle 0. Submit Answer Tries 0/99 Calculate the speed at which the rock is launched. Submit Answer Tries 0/99 To what height above sea level does the rock rise?

While at bat, your baseball teams star hitter strikes a 145-gram ball with an initial velocity of 34.7 m/s at 40.1 degrees above the horizontal. Ignoring air resistance, find the maxium height reached by the ball above its starting location in meters.
Danielle launches a ball off of a platform of height h with velocity vo at an angle 0 above the horizontal. A wall with a ball-sized hole a height H above the floor, with H > h, is a horizontal distance L = 24.0 m away from Danielle. The difference in height between H and h is one-twelfth of L, and the square of the magnitude of the velocity, v, is three-halves of the product gL. H 1 H – h = h 3 L Determine the two values of 0 that ensure the ball passes through the hole. Submit the larger angle as 0, and the smaller angle as 02.

You are going to throw a ball upward at an angle of 5.80 degrees. If you can throw it with an initial speed of 24.7 m/s, what is its initial vertical velocity component? Your Answer: Answer
A jetliner is moving at a speed of 245 m/s. The vertical component of the plane's velocity is 40.6 m/s. Given sin e = 0.165, the angle theta is equal to: Select one: O e = 10.0° e = 9.5° e = 11.5° e = 11.0° O O
A playground is on the flat roof of a city school, hb = 6.40 m above the street below (see figure). The vertical wall of the building is h = 7.70 m high, to form a 1.3-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of ? = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (a) Find the speed at which the ball was launched. m/s = (b) Find the vertical distance by which the ball clears the wall. m =(c) Find the horizontal distance from the wall to the point on the roof where the ball lands. m =
A golfer hits a shot to a green that is elevated 2.50 m above the point where the ball is struck. The ball leaves the club at a speed of 19.5 m/s at an angle of 40.0° above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands. V = i
A projectile is launched towards a hill that is d=252m away. The launch angle is θ=51.7∘ above the horizontal with an initial speed of v0=71.5m/sv0=71.5m/s.
