Answer 1

Appropriate Question:

A golf ball accelerates off a tee at 15m/s² , changing its velocity from 0m/s to 50m/s. How long did it take the ball to accelerate?

Answer:

3.3 seconds

Explanation:

As per the provided information in the given question, we have :

• Acceleration (a) = 15m/s²
• Initial velocity (u) = 0 m/s
• Final velocity (v) = 50 m/s

We have been asked to calculate time taken (t).

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

v = u + at

• v denotes final velocity
• u denotes initial velocity
• a denotes acceleration
• t denotes time

⇒ 50 = 0 + 15t

⇒ 50 = 15t

⇒ 50 ÷ 15 = t

⇒ 3.3 seconds = t

∴ Time taken is 3.3 seconds.

First equation of motion :

• v = u + at

Second equation of motion :

• s = ut + ½at²

Third equation of motion :

• v² = u² + 2as
