A ball is kicked at ground level with an initial velocity of 19 m/s in the horizontal direction and 12 m/s in the vertical direction. The ball hits the ground at a speed of 22.47 m/s and remains in the air for 2.4 seconds. What maximum height is attained by the ball in meters?

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of 17.0 m/s. The cliff is h = 51.0 m above a flat horizontal beach, as shown in the figure below. How long after being released does the stone strike the beach below the cliff? (s) With what speed and angle of impact does the stone land?      ( m/s)      ( ° below the horizontal)

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

Problem 8: A person is standing on top of a building. While standing at the edge of the building the person throws a water balloon downward with a speed of 24 m/s and at an angle of 36° below the horizontal. It takes 3.1 s for the water balloon to hit the person's friend. Part (a) How high is the building in meters? Numeric : A numeric value is expected and not an expression. h = Part (b) How fast is the water balloon moving when it hits the friend on the ground? Give your answer in m/s. Numeric : A numeric value is expected and not an expression. v= Part (c) What was the horizontal distance between the friend on the ground and the building in meters? Numeric : A numeric value is expected and not an expression. dx = %3!

An archer fires an arrow straight up into the air with a speed vo = 23 m/s. Neglect air resistance. find the maximum height reached by the arrow, in meters

This problem requires a second answer, as demonstrated by this error when I attempt to submit my answer: "Your submission doesn't have the correct number of answers. Answers should be separated with a comma." Please help me find this elusive second answer.

A missile silo is used to launch military rockets vertically upward out of the silo, giving the rocket an initial speed of 79.6 m/s at ground level. As the rocket clears the silo, the engines fire, and the rocket accelerates upward at 3.90 m/s2 until it reaches an altitude of 1,080 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s². (You will need to consider the motion while the engine is operating and the free-fall motion separately. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Determine the velocity of the rocket (in m/s) at the end of the engine burn time and also the burn time (in s). (For the velocity, indicate the direction with the sign of your answer.) velocity at end of engine V = 92.22 Check your kinematic equation relating vo, V1, ay, and AYo → 1 (where velocity of rocket as it clears the silo, v, = velocity of the rocket at…

An Olympic diver is on a diving platform 4.5 m above the water. To start her dive, she runs off of the platform with a speed of 1.3 m/s in the horizontal direction. Determine the diver's speed just before she enters the water. 4.7 m/s 9.5 m/s 6.4 m/s 0 m/s

A crossbow bolt is fired horizontally over level ground toward a target 37.4 m away. The bolt hits the target 0.24 m below the height at which it was fired.what was the initial speed of the bolt in m/s?

A 0.2 kg rock is projected from the edge of the top of a building with an initial velocity of 7.56 m/s at an angle 58° above the horizontal. Due to gravity, the rock strikes the ground at a horizontal distance of 10 m from the base of the building. Assume: The ground is level and that the side of the building is vertical. The accelera- tion of gravity is 9.8 m/s2. 58 h 10 m How tall, h, is the building? Answer in units of m. 7.56 m/s Building
