A parachutist descending at a speed of 11.80 m/s loses a shoe at an altitude of 50.30 m.
When does the shoe reach the ground?
When does the shoe reach the ground?

To avoid solving quadratic equation first find the fianl vleocity as it reaches the ground.
v ^2 = u^2 + 2as = 11.8^2 + 2*9.8*50.3 = 1125.12
v = 33.54m/s
from t = v-u/ g = 33.54-11.8 / 9.8 = 2.22 s
