2.7 / 2.2
(44-39)/2.2
The car was going 39 m/s at the beginning and speeded up during the 2.2 s
The jogger never got going more than 2.7 m/s
Which went further during the 2.2 s ? LOL
jogger d = (1/2 )(acceleration from part a) * 2.2^2
car d = 39*2.2 + (1/2) (accelration of car from part b) *2.2^2
A jogger accelerates from rest to 2.7 m/s in 2.2 s. A car accelerates from 39.0 to 44.0 m/s also in 2.2 s.
(a) Find the acceleration (magnitude only) of the jogger.
(b) Determine the acceleration (magnitude only) of the car.
(c) Does the car travel farther than the jogger during the 2.2 s?
Yes
No
Equal
If so, how much farther?
m
