In the figure, you throw a ball toward a wall at speed 39.0 m/s and at angle θ0 = 41.0˚ above the horizontal. The wall is distance d = 18.0 m from the release point of the ball. (a) How far above the release point does the ball hit the wall? What are the (b) horizontal and (c) vertical components of its velocity as it hits the wall?
In the figure, you throw a ball toward a wall at speed 26.0 m/s and at angle 0o = 42.0° above the horizontal. The wall is distance d = 24.0 m from the release point of the ball. (a) How far above the release point does the ball hit the wall? What are the (b) horizontal and (c) vertical components of its velocity as it hits the wall?
A stone is thrown from a hill at an angle of 60 degree to the horizontal with an initial velocity of 100 ft per sec. After hitting level ground at the base of the hill, the stone has covered a horizontal distance of 500 ft. How high is the hill?
In the figure, a ball is thrown leftward from the left edge of the roof, at height h above the ground. The ball hits the ground 2.10 s later, at distance d = 26.0 m from the building and at angle θ = 65.0° with the horizontal. (a) Find h. (Hint: One way is to reverse the motion, as if on videotape.) What are the (b) magnitude and (c) angle relative to the horizontal of the velocity at which the ball is thrown (positive angle for above horizontal, negative for below)?
A girl throws a ball at a vertical wall 4 m away as shown in Figure. The ball is 2 m above ground when it leaves the girl's hand with an initial velocity of??⃗0 = (10 ??/??)(??̂+ ??̂) or 10√2 ??/?? at 45º. When the ball hits the wall, the horizontal component of its velocity is reversed; the vertical component remains unchanged. Where does the ball hit the ground?
In the figure here, a ball is thrown up onto a roof, landing 3.70 s later at height h = 24.0 m above the release level. The ball's path just before landing is angled at θ = 50.0˚ with the roof. (a) Find the horizontal distance d it travels. (Hint: One way is to reverse the motion, as if it is on a video.) What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's initial velocity?
A student standing on a cliff throws a stone from a vertical height of d=8.0m�=8.0m above the level ground with velocity v0=24m/s at an angle θ=15 below the horizontal, as shown. It moves without air resistance. Use a Cartesian coordinate system with the origin at the initial position of the stone. With what speed, in meters per second, does the stone strike the ground?
An object rolls off a tabletop with a horizontal velocity v0x = 18 m/s. The table is at a height y0 = 1.2 m, above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, its horizontal x-axis lying directly beneath the object’s trajectory, and its vertical y-axis pointing up. How long, in seconds, is the object falling before it hits the floor?
In the figure, a ball is thrown leftward from the left edge of the roof, at height h above the ground. The ball hits the ground 1.40 s later, at distance d = 27.0 m from the building and at angle θ = 66.0° with the horizontal. (a) Find h. (Hint: One way is to reverse the motion, as if on videotape.) What are the (b) magnitude and (c) angle relative to the horizontal of the velocity at which the ball is thrown (positive angle for above horizontal, negative for below)? I just need (c) solved. The answer is not 56.10 degrees.
An archer fires an arrow at a target that is a horizontal distance d = 55 m away; the bull’s-eye of the target is at same height as the release height of the arrow. 1. At what angle, in degrees above the horizontal, must the arrow be released to hit the bull’s-eye if the arrow's initial speed is 35 m/s?
A squirrel is launched due west from a height of 10 meters with an initial velocity of 80 meters per second atan angle of 60 degrees above horizontal. A strong wind blowing directly out of the north causes the squirrel toaccelerate south at a rate of 2 m/s^2. All of this takes place in my backyard where acceleration due to gravity is 7 m/s2 (a) With the positive y–axis oriented north, the positive x–axis oriented east, and the positive z–axis up into the sky, findthe vector equation for the path of the squirrel. (b) Find the time when the squirrel is at her maximum height.
robin hood shoots an arrow at a target that is a horizontal distance d = 75m away; the bullseye of the target is at the same height as the release height of the arrow. at what angle, in degrees above the horizontal, must the arrow be released to hit the bullseye if the arrows initial speed is 35m/s?
