A rock is thrown horizontally from a bridge with a velocity of 10.0 m/s. It takes the rock 2.9 s to strike the water below. What is the magnitude of the velocity of the rock just before it hits the water?
A rock is thrown horizontally from a bridge with a velocity of 10.0 m/s. It takes...
A rock is thrown horizontally with a speed of 20 m/s from a vertical cliff of height 25 m. What is the velocity (magnitude and direction counterclockwise from the +x-axis, which is the initial horizontal direction in which the rock was thrown) of the rock just before it hits the ground? Magnitude - Direction - degrees
A rock Is thrown horizontally with a speed of 17 m/s from a vertical cliff of helght 31 m (a) How long does it take to reach the horizontal ground below? 2.515 (b) How far wll It land from the base of the cllff? 42.759 (c) What is the velocity (magnitude and direction counterclockwise from the +x-axis, which is the initial horizontal direction in which the rock was thrown) of the rock just before it hits the ground?

Consider a rock thrown off a bridge of height 79.8 m at an angle theta = 25 degree with respect to the horizontal as shown in Figure P4.20. The initial speed of the rock is 10.5 m/s. Find the following quantities: the maximum height reached by the rock the time it takes the rock to reach its maximum height the time at which the rock lands how far horizontally from the bridge the rock lands the velocity of the rock...

What is its kinetic energy as it hits the water? 2 A 2.00 lb rock is dropped from a bridge to the water 50.0 ft below. a. What is its velocity as it hits the water? b. What is its kinetic energy as it hits the water? 3. A pile driver weighs...
A girl throws a rock horizontally with a speed of 12 m/s from a bridge. It falls 2.28 s before hitting the water below. Neglect air resistance. (a) How high is the bridge from the water below? (b) How far horizontally does the rock travel before striking the water?
7. A ball is thrown vertically downward from the edge of a bridge 24.0 m high with an initial speed of 12.0 m/s. The ball falls all the way down and strikes the water below. Determine the time it takes the ball to strike the water. 3.75 8. A photographer in a helicopter ascending vertically at a constant rate of 1.2 m/s accidentally drops m above the ground. (a) How long will it take the camera to reach the ground?...
A rock is dropped from a bridge to the water below. It takes 2.4 s for the rock to hit the water. Express your answers in standard SI units. a. What is the speed of the rock as it hits the water? b. How far did the rock fall?
A ball is thrown horizontally from the top of a 55.0-m building and lands 106.8 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.) How long (in s) is the ball in the air? s (b) What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.) m/s (c) What is...
