As preparation for this problem, review Conceptual Example 9. From the top of a cliff overlooking a lake, a person throws two stones, as shown in the drawing. The cliff is 25.4 m high. The two stones described have identical initial speeds of v0 = 13.4 m/s and are thrown at an angle θ = 37.8∘, one below the horizontal and one above the horizontal. What is the distance between the points where the stones strike the water? Neglect air resistance. Number Units

As preparation for this problem, review Conceptual Example 10. The drawing shows two planes each dropping an empty fuel tank. At the moment of release each plane has the same speed of 182 m/s, and each tank is at the same height of 3.72 km above the ground. Although the speeds are the same, the velocities are different at the instant of release, because one plane is flying at an angle of 15.0∘ above the horizontal and the other is flying at an angle of 15.0∘ below the horizontal. Find the (a) magnitude and (b) direction of the velocity with which the fuel tank hits the ground if it is from plane A. Find the (c) magnitude and (d) direction of the velocity with which the fuel tank hits the ground if it is from plane B. In each part, give the direction as a positive angle with respect to the horizontal. Plane B

A projectile is fired from the edge of a cliff as shown in the figure at an angle of 30∘ above the horizontal. The cliff is 20 m high. The initial velocity is 13.4 m/s. The projectile reaches maximum height at point P and then falls and strikes the ground at point Q. How far from the base of the cliff does the projectile land (in m)? Neglect air resistance and use g = 9.81m s2 as the magnitude of the acceleration due to gravity.

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v→0 = 17.5 m/s. The cliff is h = 38.0 m above a flat, horizontal beach as shown in the figure. (a) What are the coordinates of the initial position of the stone? x0 = m y0 = m (b) What are the components of the initial velocity? v0x = m/s v0y = 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? v→f = m/s θ = ∘ below the horizontal
