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?
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.
