A VW Beetle goes from 0 to 64.4 mi/h with an acceleration of +2.32 m/s^{2}.

(a) How much time does it take for the Beetle to reach this speed?

____ s

(b) A top-fuel dragster can go from 0 to 60.0 mi/h in 0.600 s. Find the acceleration of the dragster.

____ m/s^{2}

Thank you for the opportunity to help you with your question!

first convert miles per hour into meter per second

( 1 mile = 1609.34 m)

( 1 hour = 60*60s=3600s)

1) 64.4 mi/h = 64.4 * 1609.34 m / 3600s

= 28.7893 m/s

time taken = velocity change/ acceleration

= 28.7893 - 0 / 2.32

= 12.4091 seconds................................ANSWER

2) 60.0 mi/h = 60*1609.34 / 3600

= 26.8223

acceleration = velocity change/ time taken

= 26.8223- 0 / 0.6

= 44.7039 m/s^2......................................ANSWER
