Question

A bus starts to move from rest if its velocity becomes 90 km per hour after 8 speed calculate its acceleration.

write with full process.
answer=3.13ms–²
​

Answer 1

Acceleration, a = 3.13 m/s²

Step-by-step explanation:

Given the following data;

Initial velocity = 0 m/s (since it's starting from rest).

Final velocity = 90 km/h

Time = 8 seconds

Conversion:

90 km/h = (90 * 1000)/3600 = 25 m/s

To find the acceleration, we would use the first equation of motion;

V = U + at

Where;

V is the final velocity.

U is the initial velocity.

a is the acceleration.

t is the time measured in seconds.

Substituting into the equation, we have;

25 = 0 + a*8

25 = 8a

Acceleration, a = 25/8

Acceleration, a = 3.125 ≈ 3.13 m/s²
