Question

Please help me out with this, i do not need just an answer; I would like an explanation of how to sort out the problem so i know what I am doing? here is the problem: A VW Beetle goes from 0 to 60.0 mi/h with an acceleration of +2.35 m/s^2. (a) How much time does it take for the beetle to reach this speed? (b) A top-fuel dragster can go from 0 to 30 mi/h in 0.600 s. Find the acceleration (in m/s^2) of the dragster?

Answer 1

First of all, you need to know 60 Mph in m/s.

Answer 2

Once you find that, you divide the final velocity by the initial velocity. That will give you the amount of it will take to accelerate to the final velocity.In the other instance, you need to do the same thing with the final speed, and then divide the final velocity by the time taken to accelerate.

Answer 3

convert mi/h to m/s then use v=vo+at

Answer 4

for b use a=change in velocity/time

Answer 5

Thank you so much, so helpful:)
