Which explorer sailed for both the netherlands and england in search of the northwest passage Understanding that although the shape of an object may change, the mass of the object stays the same is an example of a) object permanence. Objects X and Y are connected by a string of negligible mass and suspended vertically over a pulley of negligible mass, creating an Atwood's machine, as shown in the figure. The work done by friction while sliding down the ramp will be the same expression you used to determine the work done moving up the ramp since the force of friction and distance over which it acts are the same in both directions of travel. A The only acceleration is gravity the rider must keep the wheel from falling, which involves a little bit of pulling on the handlebars and a some pushing with the feet on the pedals.
