A stone with a weight of 5.26 Newton is launched vertically from ground level with an initial speed of 24.0 m/s, and the air drag on it is 0.264 N throughout the flight.
(a) Determine the maximum height reached by the stone and
(b) Find its speed just before it hits the ground?
The position function x(t) of a particle moving along an x axis is x = 4.5 - 4.5t2, with x in meters and t in seconds.
Assume, instead, that the observer had been moving away from Earth with a speed of 0.80c. How much time would observer have measured for the car to be filled in this case.
