Oh yeah, my bad... velocity times mass... I always mix up with impulse lol :S, but yeah I guess friction is part of the experiment ? However... when you take the bucket of sand off, the friction stays the same ?
Homework Statement
Ok so my teacher used this example in class, he had this flat wheeled cart rolling on the floor. The object was to release a bucket of sand on top of the flat cart to see if the cart would slow down or accelerate. Easily, all of us the students predicted that the cart would...

34.8g (1mol/____g) = ______mol
The Attempt at a Solution
34.8g (1mol/58.44g) = 2033.712mol
Not quite sure if this is how things work, hopefully you can give me a few hints.
I have an awnser sheet and it says 2m/s... I'm supposed to find what force pushed the cart above the second hill which I assume is kinetic energy but I have no mass which I don't understand...
Homework Statement
I have to find the speed needed to push a cart on top of a hill and I only have the height as a number.

A boy places his matchbox car at the top of the track he has set up with his brother. If the track starts atop the 55 cm toy box, descends to the...
1)Well depending on steel's density, it would either find itself at the botom of water or float to the top without even following the pattern
2)Friction ?
1) No, that's not what I'm talking about. What else is different about the moon, other than the 1/6 gravity?
Its lighter
2) No, assume that they both have enough friction on the ramp so that they do not slip. What is the main difference between steel and rubber (other than mass density)...
