-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.v = 33.......
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?

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
