Expert Solution
Step 1
Given helicopter is descending at constant and wrench is dropped at t=0
(a)
Let helicopter is moving in negative y-direction.
Initial velocity of dropping object is equal to velocity of helicopter.
Wrench is falling under gravity, so a=-g
After time t speed is;
Using equation of motion we have,
Plugging value of velocity and acceleration in above equation we get,
so,
