Question

An object falls for 2 seconds after being dropped from rest. Its velocity is:

Answer 1

V = 19.62 [m/s]

Step-by-step explanation:

To solve this problem we must use the following equation of kinematics:

`v=v_(o) +(g*t)`

where:

V = final velocity [m/s]

Vo = initial velocity = 0

g = gravity acceleration = 9.81 [m/s²]

t = time = 2 [s]

V = 0 + (9.81*2)

V = 19.62 [m/s]
