A volleyball is thrown with an initial velocity of 30 m/s at an angle 40° above the horizontal? Answer the Question: What is the horizontal distance from the starting point will the volleyball attains its original level?

A ball is launched horizontally from the top of a 100 m tall building and lands 150 m (horizontal distance) from the base of the building. Ignore air resistance. (a) How long in seconds is the ball in the air? (b) What must have been the initial horizontal component of the velocity in m/s? (c) What is the vertical component of the velocity in m/s just before the ball hits the ground? (d) What is the speed or magnitude of the resultant velocity (including both the horizontal and vertical components) in m/s of the ball just before it hits the ground?

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vo = 23.0 m/s. The cliff is h = 61.0 m above a flat, horizontal beach as shown in the figure. h (a) What are the coordinates of the initial position of the stone? X0 = m Yo = (b) What are the components of the initial velocity? 0x m/s Voy* m/s (c) Write the equations for the x- and y-components of the velocity of the stone with time. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not include units in your answer.) Vx= Vy= (d) Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.) X= y = (e) How long after being released does the stone strike the beach below the cliff? S (f) With what speed and angle of impact does the stone land? m/s ° below the horizontal

A cannon ball is fired with an initial speed of 123 m/s at an angle of 60 degrees from the horizontal.Express the initial velocity as a linear combination of its unit vector components.Find the maximum height reached by the cannon ball and the time needed to reach the maximum height.Find the speed of the cannon ball at the maximum height and the magnitude of its acceleration.

A projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?

In an article on the use of the sling as a weapon, the author states that a skilled slinger can sling a rock a distance of about 384 m. What is the minimum speed the rock must have when it leaves the sling to travel exactly 384 m? To solve this problem it will be necessary to first determine the required launch angle of the projectile. What launch angle must the projectile have in order to find the minimum speed required to achieve a given horizontal distance?

A ball is thrown vertically upward with an initial speed of 88 ft/sec from the base A of a cliff with H = 60 ft. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the magnitude of the impact velocity vg. Neglect air resistance and the small horizontal motion of the ball. Answers: h = i ft t = i sec VB = i ft/sec

Suppose an outfielder throws a baseball with an initial speed of 12 m/s in a direction 30° up from the horizontal. Use a trajectory diagram to determine the height of the peak of its trajectory in reality. I suggest using a time step of Δt = 0.2s and a scale of 1.0 m (in reality) = 2.0 cm (on diagram).   The height of the peak of its trajectory in reality is ______ m.

If the ramp is now tilted upward so that “takeoff angle” is now 7.0 degrees above the horizontal, what is the new minimum speed?

A student standing on a cliff that is a vertical height d = 8.0 m above the level ground throws a stone with velocity v0 = 25 m/s at an angle θ = 17 ° below horizontal. The stone moves without air resistance; use a Cartesian coordinate system with the origin at the stone's initial position. With what speed, vf in meters per second, does the stone strike the ground? Recall that the ball will have a final velocity along the y-axis and the x-axis and these components need to be added together with the Pythagorean theorem in order to find the resultant velocity.
