1) The maximum tension an elevator cable can withstand cable can withstand before breaking is 'T'. Assume the mass of the elevator is 'm'. Drawn a free-body diagram of the elevator and use Newton's second law to find an expression for the maximum acceleration of the elevator. What is the direction of this acceleration?

2) A diver runs horizontally off a vertical cliff with a speed of 3m/s and hits the water below 4 seconds later. Ignore air resistance.

A)How high was the cliff?

B)How far away (horizontally) from the base of the cliff does the land?

 

C) plot the diver's x-axis (horizontal) and y-axis (vertical) displacements as functions of time.

 

D) plot the diver's x-axis (horizontal) and y-axis (vertical) velocities as functions of time.
