Question

a busis moving with the initial velocity 10m/s . after 4 seconds, the velocity becomes 30m/s . find the acceleration produce by bus,......please I need help​

Answer 1

Answer:

5 m/s²

Explanation:

Use the acceleration formula: $a=\frac{v_f-v_i}{t}$

• a = acceleration (m/s²)

• vf = final velocity (m/s)

• vi = initial velocity (m/s)

• t = time (s)

Based on the information given to us by the prompt, we know:

• vi = 10 m/s

• vf = 30 m/s

• t = 4 s

Substitute these values for the variables to calculate the acceleration:

$a=\frac{30-10}{4}\\\\a=\frac{20}{4}\\\\a=5$

Therefore, the acceleration of the bus is 5 m/s².
