A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.50 m/s at an angle of 24.0° below the horizontal. It strikes the ground 6.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? m (b) Find the height from which the ball was thrown. m (c) How long does it take the ball to reach a point 10.0 m below the level of launching? s

A cannonball is launched from the top of a flat mountainside, which slopes upwards at35 degrees with respect to the horizontal. The cannonball exits the cannon moving at150 m/s, at an angle of 55 degrees with respect to the horizontal.a) How much time (in seconds) elapses between the moment the cannonball isfired and the moment it lands on the mountainside.b) How far down the mountainside (in meters) does the cannonball land?

A football is kicked at 25.0 m/s at an angle of 29.0° above the horizontal. Assume it starts 1.00 m above ground level. (Neglect any effects due to air resistance.) Describe the velocity vector of the ball in terms of its x- and y-components, U, and u,, respectively, when it is 4.50 m above ground level and still moving upward. U₂ = 21.86 U)= m/s 23.78 Describe the velocity vector of the ball in terms of its magnitude u and angle 0 above the horizon when it is 4.50 m above ground level and still moving upward. m/s 9.38 0= Incorrect 23.22 m/s Incorrect

A ball thrown horizontally at vi = 25.0 m/s travels a horizontal distance of d = 50.0 m before hitting the ground. From what height h was the ball thrown?

You throw a rock from the upper edge of a 85.0-m vertical dam with a speed of 28.0 m/s at 65.0° above the horizon. 1) How long after throwing the rock will you see it hit the water? (Neglect any effects due to air resistance.) (Express your answer to three significant figures.) Submit S 2) How far from the bottom of the dam does the rock land? (Neglect any effects due to air resistance.) (Express your answer to three significant figures.) Submit m

A placekicker is about to kick a field goal. The ball is 21.7 m from the goalpost. The ball is kicked with an initial velocity of 19.1 m/s at an angle above the ground. Between what two angles, 0₁ and 02, will the ball clear the 2.67-m-high crossbar? Give your answers as (a) the smaller angle and (b) the larger angle. (Hint: The following trigonometric identities may be useful: sec 0 = 1/(cos) and sec²0 = 1 + tan²0.) (a) Number (b) Number Units Units 0₂

A projectile is launched horizontally with a speed of 12.0 m/s from the top of a 78.0m cliff. How far from the base of the cliff is the projectile when it hits the ground?

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.

A snowball rolls off a barn roof that slopes downward at an angle of 40°. The edge of the roof is 14.0 m above the ground, and the snowball has a speed of 7.00 m/s as it rolls off the roof. Ignore air resistance, how far from the edge of the barn does the snowball strike the ground if it doesn't strike anything else while falling? If a man 1.9 m tall is standing 4.0m from the edge of the barn, will he be hit by the snowball?

A skier leaves the end of a horizontal ski jump at 21.0 m/s and falls through a vertical distance of 3.30 m before landing. (a) Neglecting air resistance, how long does it take the skier to reach the ground? s (b) How far horizontally does the skier travel in the air before landing? m
