The velocity changes from 35m/s to 60m/s in 3 seconds. What is its acceleration?
Acceleration is defined as the rate of change of velocity with time. It is calculated using the formula:
$a = \frac{v - u}{t}$
Here,
Initial velocity (u) = 35 m/s,
Final velocity (v) = 60 m/s,
Time (t) = 3 s.
So,
$a = \frac{60 - 35}{3}$
$a = \frac{25}{3} \approx 8.33\ \text{m/s}^2$
Hence, the correct answer is option (C) 8.33 m/s².
