A particle initially is moving at a velocity with Cartesian components (5.0 m/s, 4.0 m/s) and 5.6 s later it is moving at a velocity with components (8.0 m/s, 0.0 m/s).
What is the magnitude of its average acceleration, in m/s2?
A rock is thrown off a vertical cliff at an angle of 65 degrees above horizontal. The cliff is 67.2 m high and the ground extends horizontally from the base. The initial speed of the rock is 24.4 m/s. Neglect air resistance.
a) How high above the ground, in meters, is the rock 2.03 s before it hits the ground?
b) How far horizontally from the cliff, in meters, is the rock 2.03 s before it hits the ground?
A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of 18.0 m/s. The cliff is 50.0 m above a flat, horizontal beach, as shown in Figure P3.24.
