A jet plane is rising vertically with a velocity of 10m/s. It has reached a certain height when the pilot drops a coin, which takes 4sec to hit the ground. Assuming that there is no resistance to the motion of the coin, the height of the place and the velocity of the coin on impact with the ground are:

A.

38.4 m, 28.7 m/s

B.

38.4 m, 29.2 m/s

C.

26.5 m, 13.5 m/s


D.

26.5 m, 28.7 m/s
