Problem #1 Working for the latest Hollywood production, a brave stuntwoman in her car rides off the horizontal surface of a cliff with an initial horizontal velocity of magnitude v = 40.0 m/s and into the ocean waters, as shown in the picture below. The edge of the cliff rises to a height H= 60.0 m above the water. Your job is to determine whether she will have enough time to leave the vehicle during flight, and whether she will be close enough to the base of the cliff to be rescued if something goes wrong. s 9 0

Expert Solution
Step 1
Given,
Initial horizontal velocity,
Height of the cliff, H=60 m
(e.) Let us consider the horizontal distance travelled from the base of the cliff be x .
By equation of kinematics we have,
.......(1)
The time taken to reach the water from the cliff is
We know there is no acceleration in horizontal direction,
so
Thus equation (1) implies,
Thus, the horizontal distance travelled by the car before slamming the water is 140 m
Step 2
(f.) Initially the y-component of velocity is
Let be the y-component of final velocity
By equation of kinematics,
The y-component of final velocity before slamming the water is 34.29 m/s.
