Which of the following is INCORRECT about projectile motion with the same initial and final elevations? a. The total time of flight is twice the time to reach the maximum height. b. The magnitude of the acceleration at the maximum height is 9.8 m/s2. c. At its maximum height, the velocity of the projectile is zero. d. Only the vertical component of the motion is accelerating.
A rescue helicopter is hovering over a person whose sailboat has capsized. One of the rescuers tosses a life preserver straight down to the person with an initial speed of 1.25 m/s and observes that it takes 1.75 s to reach the water. How high above the water was the preserver released? Note that the downdraft of the helicopter reduces the effect of air resistance on the falling life preserver, so that an acceleration equal to that due to gravity is reasonable.
