Question

A bicycle and rider travel along a road. Which is true?
A. The bicycle and the rider undergo translation.
B. Only the rider undergoes a translation.
C. Only the bicycle undergoes translation.
D. Neither the bicycle nor the rider undergoes a translation.

**Would it be A? Since they both are going in a straight line along the road?

Answer 1

i would say C would be the answer because the bike is moving

Answer 2

the rider is moving too

Answer 3

unless something pulled him back to stop him and the bike keeps going

Answer 4

Yes...both bike and the rider are going through translational motion but the wheels are also going through rotational motion in addition.

Answer 5

it's like the rider is walking and pulling the bike alongside?

Answer 6

okay thanks for the input

Answer 7

ohh so what does that mean? is A correct? :O

so person + bike=translational
wheels=rotational?

Answer 8

I thought of it has the guy on the bike is stationary while the bike is moving...

Answer 9

depends on frame of reference
the rider is not moving with reference to bicycle

the bicycle is not moving with reference to rider

both are moving with reference to road

Answer 10

Person + Bike (on whole) = Translational
wheels (rotational + Translational)

Answer 11

A. the rider is moving too because you have to push the pedals with your feet. the bike moves too

Answer 12

Answer 13

Yes @ganeshie8 said a very important point

Answer 14
