Problem 44PE

 Problem 44PE

A rescue helicopter is hovering over a person whose boat has sunk. One of the rescuers throws a life preserver straight down to the victim with an initial velocity of 1.40 m/s and observes that it takes 1.8 s to reach the water. (a) List the knowns in this problem. (b) How high above the water was the preserver released? Note that the downdraft of the helicopter reduces the effects of air resistance on the falling life preserver, so that an acceleration equal to that of gravity is reasonable.

Solution  44 PE

A rescue helicopter is hovering over a person whose boat has sunk. One of the rescuers throws a life preserver straight down to the victim with an initial velocity of 1.40 m/s and observes that it takes 1.8 s to reach the water.

We have to list the knowns in the problem and also how high above the water was the preserver released?o

a.)

Its a problem of one-dimensional motion involving gravity and can be solved using kinematic equation for objects in free fall where acceleration is .

The knowns in this problem are initial position, initial velocity ,time in free fall

b.)

From...
