There are three possible hypotheses:
Take your pick and then use the data to test your hypothesis.

A cylinder is a solid figure that can both roll and slide. Its shape and symmetry allows it to roll smoothly along a surface, and its circular base provides stability for sliding. Both of these properties make it suitable for applications such as wheels and rollers.
8 rolls
8 rolls of pennie’s 6rolls of nickels 3 rolls of dimes 9rolls of quarters
Assuming you mean each roll has 25 coins, 90 rolls would be $112.50.
Yes
because you are determining whether distance is affected by the wheels, wheels would thus be the manipulated variable. I recommend using different wheel sizes or eeven hardness, but your best bet would be to test size.
wheelbarrow
No because mass doesn't means how it affect far it rolls
A car rolls by using it's wheels.
Your wheels should point into the curb, so if vehicle rolls it will stop on the curb .
how does increasing the height of a ramp affect how far a ball rolls down the ramp
no
when you are parking UPhill.supposedly then if the car rolls the wheels will contact the curb and stop the car. Down hill turn to the right
the car on launoulum will roll farter
To the left, so if the car rolls it will hit the curb and not swing into traffic.
