A ball rolls down, an inclied plane and acquires a velocity v_(r) when it reaches the bottom of the plane. If the same ball slides without friction and acquires rolling from the same height down an equally inclined smooth plane and acquires a velocity v_(s). Then which of the following statement(s) is/are not correct ?

1.	A ball rolls down, an inclied plane and acquires a velocity v_(r) when it reaches the bottom of the plane. If the same ball slides without friction and acquires rolling from the same height down an equally inclined smooth plane and acquires a velocity v_(s). Then which of the following statement(s) is/are not correct ?
Answer» `v_(r)ltv_(s)`, because a work is done by the rolling ball against the frictional force `v_(r)gtv_(s)`, because the angular velocity aquired MARKES the rolling ball to travel faster `v_(r)=v_(s)`, because kinetic energy of the two balls is same at the BOTTOM of the planes `v_(r)ltv_(s)`, because the rolling ball acquires rotational as WELL as TRANSLATIONAL kinetic energy Answer :A::B::C
