Physics, Motion in a straight line Class 11.
Q: A parachutist after bailing out falls 50m without friction. When parachute opens, it decelerates at 2 m/s^2
. He reaches the ground with a speed of 3ms. At what height, did he bail out ?
Ans I got: I got V = Root of 980, however i dont understand why acceleration (here:2m/s^2) is considered negative
although it says deceleration it still goes in the direction of displacement and velocity
