Good Day

Problem:

a flower falls from a windowsill 9.2 meters above the sidewalk.

1. How fast is the flower pot moving when it strikes the ground?

Given Data:

a (acceleration) = 9.8 m/s²

d (distance) = 9.2 m

Vf (final velocity) = ? unknown

Vi (initial velocity) = 0 m/s

Solution:

We can use the formula Vf = √2ad

Vf = √2ad

    = √2 × 9.8 m/s²  × 9.2 m

   = √180.32 m²/s²

    = 13.43 m/s

Answer:

13.43 m/s

2. How much time will it take for the flowerpot to hit the ground?

Given Data:

a (acceleration) = 9.8 m/s²

Vf (final velocity) = 13.43 m/s

Vi (initial velocity) = 0 m/s

t (time) = ? unknown

Solution:

we use the formula t = Vf-Vi/a

t = Vf-Vi/a

 = (13.43 m/s - 0 m/s)/ 9.8 m/s²

  = 13.43 m/s  / 9.8 m/s²

  =  1.37 seconds

Answer:

1.37 seconds
