But how can you go through step by step with me?
Velocity = gravity x time
velocity = 4.3 m/s
gravity (constant) = 9.8 m/s/s
4.3 = 9.8 x time
4.3 / 9.8 = 9.8 x time / 9.8
4.3 / 9.8 = time
.439 = time
velocity = 4.3 m/s
gravity (constant) = 9.8 m/s/s
4.3 = 9.8 x time
4.3 / 9.8 = 9.8 x time / 9.8
4.3 / 9.8 = time
.439 = time
