Answer 2

Answer :

Given -

• u = 0 m/s
• v = 49 m/s
• g = -9.8 m/s²

To Find -

• Height or s ?

Solution -

We know that, v² - u² = 2gs.

Hence,

⇒ 49² - 0² = 2*-9.8*s

⇒ 2401 = 19.6*s

⇒ s = 2401/19.6

⇒ s = 122.5 m

Hence, the Height which the ball rises is 122.5 m.

Equations of Motion :

• v = u + at
• s = ut + ½gt²
• v² - u² = 2gs
