On two occasions you accelerate uniformlyfrom rest along an on-ramp in order to merge into interstate trafficat 65 mi>h. On-ramp A is 200 m long and on-ramp B is 400 m long.(a) Is your acceleration along on-ramp A greater than, less than,or equal to your acceleration along ramp B? (b) Choose the bestexplanation from among the following:I. The shorter acceleration distance on ramp A requires a greateracceleration.II. In each case, you start from rest and have the same final speed.III. The greater distance traveled on ramp B requires a greater acceleration.

On two occasions you accelerate uniformly
from rest along an on-ramp in order to merge into interstate traffic
at 65 mi>h. On-ramp A is 200 m long and on-ramp B is 400 m long.
(a) Is your acceleration along on-ramp A greater than, less than,
or equal to your acceleration along ramp B? (b) Choose the best
explanation from among the following:
I. The shorter acceleration distance on ramp A requires a greater
acceleration.
II. In each case, you start from rest and have the same final speed.
III. The greater distance traveled on ramp B requires a greater acceleration.
