A dragster in a race accelerated from stop to 60 m/s by the time it reached the finish line. The dragster moved in a straight line and traveled from the starting line to the finish line in 8.0 sec. What was the acceleration of the dragster?

Answer 1

To find the acceleration of the dragster, we can use the following formula:

acceleration (a) = change in velocity (Δv) / time (t)

The change in velocity is the final velocity (60 m/s) minus the initial velocity (0 m/s). The time is given as 8.0 sec. Plugging in these values into the formula, we get:

a = (60 m/s - 0 m/s) / 8.0 sec

Calculating this expression, we find:

a = 60 m/s / 8.0 sec

Simplifying further, we obtain:

a = 7.5 m/s²

Therefore, the acceleration of the dragster is 7.5 m/s².
