A hiker throws a stone from the upper edge of a vertical cliff. The stone's initial velocity is 25.0 m / s directed at 40.0° with the face of the cliff, as shown in the figure. The stone hits the ground 3.75 s after being thrown and feels no appreciable air resistance as it falls.(a) What is the height of the cliff?(b) How far from the foot of the cliff does the stone land?(c) How fast is the stone moving...

A rock is thrown off a cliff at an angle of 51° above the horizontal. The cliff is 130 m high. The initial speed of the rock is 20 m/s. (Assume the height of the thrower is negligible.) (a) How high above the edge of the cliff does the rock rise (in m)? (b) How far has it moved horizontally when it is at maximum altitude (in m)? (c) How long after the release does it hit the ground (in s)? (d) What is...

Zero Launch Angle - Car Drives Off a Cliff A car drives straight off the edge of a cliff that is h =40 m high. The police at the scene of the accident note that the point of impact is d =86 m from the base of the cliff. Here the initial speed v0 is unknown. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as positive y-direction. A....

A rock is dropped off the edge of a cliff and its distance s (in feet) from the top of the cliff after t seconds is s(t) = 16t. Assume the distance from the top of the cliff to the water below is 400 ft. Answer part (a) and (b). (a) When will the rock strike the water? The rock will strike the water at 5 seconds. (Type an integer or a simplified fraction.) (b) Make a table of average...
A student stands at the edge of a cliff and throws a stone horlzontally over the edge with a speed of vi = 21.5 m/s
A student stands at the edge of a cliff and throws a stone horlzontally over the edge with a speed of vi = 21.5 m/s. The cliff Is h = 50.3 m above a body of water as shown in the figure below. (a) What are the coordinates of the initial position of the stone? (Note that the origin is at the base of the cliff, where the x- and y-axes intersect.)(b) What are the components of the initial velocity of...

A student stands at the edge
of a cliff and throws a stone horizontally over the edge with a
speed of v0 = 13.5 m/s. The cliff is h = 52.0 m above a flat,
horizontal beach as shown in the figure.
(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.)...
