Question

You stand at the edge of a cliff that's 200 m high. You have two rocks, one of which you give a kick so it moves horizontally off the edge at a speed of 5 m/s, the other of which you throw at a speed of 10 m/s and an angle of $\theta = 30^\circ$ above the horizontal. How far apart do the two land from each other?

Step 1

For the rock kicked horizontally, we can use the equation: \[ h = \frac{1}{2}gt^2 \] where h is the height of the cliff (200m), g is the acceleration due to gravity (9.8 m/s^2), and t is the time it takes for the rock to hit the ground. Solving for t, we get: \[ t Show more…

You stand at the edge of a cliff that's 200m high. You have two rocks, one of which you give a kick so it moves horizontally off the edge at a speed of 5(m)/(s), the other of which you throw at a speed of 10(m)/(s) and an angle of heta =30deg above the horizontal. How far apart do the two land from each other? You stand at the edge of a cliff that's 200 m high.
