A rescue helicopter is hovering over a person whose boat has sunk. One of the rescuers throws a life preserver straightdown to the victim with an initial velocity of 2.14 m/s and observes that it takes 2.4 s to reach the water.(a) List the knowns in this problem. (Select all that apply.)Ay(b) How high (in m) above the water was the preserver released? Note that the downdraft of the helicopter reduces theeffects of air resistance on the falling life preserver, so that an acceleration equal to that of gravity is reasonable.m

The initial velocity of the life preserver is 2.14 m/sThe time taken by the preserver to reach water…

I performed a lab using a toy car to go down a ramp that was positioned at different heights. For expample: ramp height = 60 cm, ramp length = 121.92 cm, time car took to clear the ramp from start = .67 seconds, distance car traveled from end of ramp to stopping point = 1178.56 cm, mass of car = .54 kg, based off this information..... Calculate the velocity of the car at the end of the ramp just before it starts its horizontal path to its stopping point. PE = KE = (1/2) m v^2
