Question

a parachutist decided to jump of a plane calculate how far does he travels in 2 seconds knowing that he started at rest and accelerates downward at 10ms​

Answer 1

20 meters

Step-by-step explanation:

Given the following parameters

Time t = 2 seconds

Acceleration a = 10m/s²

Required

Distance covered S

Since the body started from rest, u = 0m/s

Using the equation of motion S = ut + 1/2 at²

Substitute

S = 0 + 1/2(10)(2)²

S = 5 * 2²

S = 5 * 4

S - 20m

Hence he travels 20 meters
