Dragsters are cars that reach high speeds very quickly through massive acceleration. For example, a dragster may zoom from 0 to 480 kph in 4.5 seconds. What is a dragster's average acceleration?

a) 96 m/s²
b) 106.67 m/s²
c) 106.67 km/h²
d) 96 km/h²

Final answer:

The average acceleration of a dragster accelerating from 0 to 480 kph in 4.5 seconds is 29.63 m/s², which does not match any of the provided answer options, indicating a possible error in the question.

Step-by-step explanation:

The subject of the question revolves around calculating the average acceleration of a dragster, which is a concept in physics related to motion and forces. Given that a dragster accelerates from 0 to 480 kph (which is 133.33 m/s) in 4.5 seconds, we can find the average acceleration by using the formula a = Δv / Δt, where a is acceleration, Δv is the change in velocity, and Δt is the time taken to change the velocity. Converting the velocity to meters per second (m/s), we get 133.33 m/s from 480 kph. The average acceleration (a) can be calculated as:

a = Δv / Δt
a = (133.33 m/s - 0 m/s) / 4.5 s
a = 133.33 m/s / 4.5 s
a = 29.63 m/s²

This is not one of the options provided (a or c), which may indicate a typo or error in the provided answers. The correct calculation shows an average acceleration of 29.63 m/s², which suggests that none of the options (b and d) are correct based on the values provided in the question.
