Question

If a runner with a mass of 52 kg speeds up from 2 m/s to 8 m/s in 3.2 seconds, what is his acceleration?

Answer 1

1.875 m/s²

Step-by-step explanation:

Here mass is not required by sake of formula.

we know Change in velocity over time is acceleration

• Final_v - Initial_v/time taken mathematically = acceleration

v = 8 m/s

u = 2 m/s

t = 3.2 s

Acc = 8-2/3.2

• 6/3.2
• 1.875 m/s²
