Hey could someone explain to me this problem because i tried every single variation of the rules i learned in class, v = delta d/ delta t a= delta v/ delta t ect.. and i kept getting the wrong answer.
A parachustist jumps from an airplane and freely falls y=53.2 m before opening his parachute. Thereafter, he decelerates at a=2.00 m/s2. As he reaches the ground, his speed is 3.23 m/s. How long was the parachutist in the air?
