Question

A boy rides a motorbike with a velocity of 10 m/s. He accelerates his motorbike to a velocity of 25 m/s in 5 seconds. Calculate the acceleration of the motorbike.

(A) 3 m/s²
(B) 5 m/s²
(C) 3.75 m/s²
(D) 2.5 m/s²

Answer 1

The acceleration of the motorbike is calculated using the change in velocity divided by the time taken. With an initial velocity of 10 m/s, a final velocity of 25 m/s, and a time interval of 5 seconds, the acceleration is found to be 3 m/s².

Step-by-step explanation:

To calculate the acceleration of the motorbike, we can use the formula for acceleration, which is the change in velocity (Δv) divided by the time (Δt) it takes for the change to occur. The initial velocity of the motorbike is 10 m/s, and the final velocity is 25 m/s. Since the change occurs over a period of 5 seconds, we can calculate the acceleration (a) as follows: a = Δv / Δt, a = (25 m/s - 10 m/s) / 5 s, a = 15 m/s / 5 s, a = 3 m/s². Thus, the acceleration of the motorbike is 3 m/s², which corresponds to option (A).
