Question

A runner achieves a velocity of 12.1 m/s 8.2 sec after he begins. What is

his acceleration (m/s)?

Answer 1

Given -

• Velocity (v) = 12.1 m/s
• Time (t) = 8.2 sec

To find -

• Acceleration

Solution -

★ Acceleration = velocity/ time

→ A = 12.1/8.2

→ 1.47.... m/s²

Therefore, the acceleration of the runner will be 1.47 m/s².
