a ball is thrown striaght up in the air and then falls back to earth. if the downward fall takes 2.2s, how fast is the ball traveling when it striker the ground

Respuesta :

The velocity of the ball when it strikes the ground, given the data is 21.56 m/s

Data obtained from the question

From the question given above, the following data were obtained:

  • Time to reach ground from maximum height (t) = 2.2 s
  • Initial velocity (u) = 0 m/s
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Final velocity (v) =?

How to determine the velocity when the ball strikes the ground

The velocity of the ball when it strikes the ground can be obtained as illustrated below:

v = u + gt

v = 0 + (9.8 × 2.2)

v = 0 + 21.56

v = 21.56 m/s

Thus, the velocity of the ball when it strikes the ground is 21.56 m/s
