Question

3. You stand at the edge of an enormous cliff, throw your keys upwards at 5.00 m/s, releasing them at a height 1.25 m above the top of the cliff, then watch as they fall downwards into the canyon below. a. What is the velocity of your keys as they fall past your outstretched hand, 1.25 m above the cliff top? b. Where are they 8.00 seconds after you threw them? c. What is the velocity of your keys at that moment (8.00 seconds after you threw them)?

Step 1

We can use the equation of motion for vertical motion: y = y0 + v0t + (1/2)at^2 where y is the final position, y0 is the initial position, v0 is the initial velocity, t is the time, and a is the acceleration. In this case, y = 1.25 m (the height above the cliff Show more…
