Darcel and Chandra decide to try a little experiment. They completely fill two identical cylindrical bottles with water. One is placed in a freezer until the water has turned to ice; then both bottles are placed on a short incline and allowed to roll to the bottom. Assume that the ice and bottle expand along the axis, so that the radii of both bottles are the same. Darcel asks Chandra to predict which will reach the bottom of the incline first, and to explain her reason. Which response is correct

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
