A high-speed dart is shot from ground level with a speed of 150 m/s at an angle 30° above the horizontal. What is the vertical component of its velocity after 4.0 s if air resistance is neglected? 38 m/s O 111 m/s 75m/s 130 m/s 36 m/s 90.7 m/s O 150 m/s

A ball is thrown horizontally from the top of a 56.5-m building and lands 122.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.)   What is the velocity (in m/s) (including both the horizontal and vertical components) of the ball just before it hits the ground? magnitude:  _______m/s direction: ______  ° counterclockwise from the +x-axis

An object is initially 20 meters above the ground. It is thrown upward at a speed of 4.7 m/s at an angle of 60 degrees from the horizontal. What is the horizontal component of its velocity, in m/s, at impact (when it reaches the ground)?

A boy stands 10 meters from a school building, tosses a ball toward the building with an angle of 30 degrees above the horizontal. What height does the ball strike the building with if the initial speed is 25 m/s

A cannon ball is fired at a wall that is 300 m away on level ground. The initial velocity of the cannon is 89 m/s, 40° above the horizontal. Don't assume the ball hits the wall at maximum height! What is the y-component of the ball's velocity when the ball hits the wall? h V; = 89 m/s 40° 300 m O 89.0 m/s O 9.81 m/s O 7.60 m/s O 18.2 m/s O 14.1 m/s O 2.99 m/s

Standing on the roof of a 95-m tall building, a girl holds her hand past the edge and throws a ball straight up at 8 m/s. The ball rises, then falls and strikes the ground. Considering "up" to be the positive direction, find the ball's velocity v when it is 40 m above the ground. Remember to include a "-" sign if the velocity is negative. V = m/s

A circus performer stands on a platform and throws an apple from a height of 50.0 m above the ground with an initial velocity v0 as shown in the figure below. A second, blindfolded performer must catch the apple. If v0 = 15.0 m/s,how far from the end of the platform should the second performer stand? (Assume ? = 30.0°.) ? m

A cannonball is shot from a cannon at a launch angle of 350 and an initial velocity of 147 m/s. Assuming NO air resistance, what is the intial horizontal velocity of the cannonball. 120 m/s 9.8 m/s 147 m/s 51.45 m/s Previous Page Next Page 99+ Page 2 of 5

A Supply plane needs to drop a package of food to scientists working on a glacier in Greenland.  The plane flies 97 m above the glacier at a speed of 133 m/s.  How far away from the target should it drop the package? (Hint: This is a horizontal projectile. The package has the same initial speed as the plane)

A rescue plane is flying at a speed of 98 m / s at 353 meters above the ground. If you drop a box of supplies, how far will it travel horizontally?
