Question

Calculate the

acceleration of a
boomerang that has an
initial veleocity of 2m/s
and then speeds up to
10m/s after 4 seconds

Answer 1

2 m/s²

Step-by-step explanation:

• Initial velocity = 2m/s
• Final velocity = 10m/s
• Time = 4s
• Acceleration = ?

As we know that ,

`\longrightarrow` a = v - u / t

`\longrightarrow` a = (10 - 2)m/s ÷ 4s

`\longrightarrow` a = 8/4 m/s²

`\longrightarrow` a = 2 m/s²
