Question

the figure shows two balls, m1 and m2 of the same mass. Ball 1 starts from rest and slides down a frictionless slide from a height H from the floor. Ball 2 is dropped from rest at the same time and height. At height h ball 1 falls of the incline.

Determine whether each is greater than, less than, equal to, not equal or cannot tell.

The time it takes for ball 1 to slide from H to h is _______ the time it takes ball 2 to fall the same vertical distance.

The time it takes for ball 1 to fall from h to the floor is ______ the time it takes ball 2 to fall from h to the floor.

The velocity of ball 2 when it is at height h is _______ the velocity of ball 1 when it is also at height h.

The kinetic energy of ball 2 when it is at height h is _______ the kinetic energy of ball 1 when it is also at height h.

The maximum height that ball 2 bounces up from the floor is ________ the maximum height that ball 1 bounces in from the floor. (assume no loss in energy).

Explanation / Answer

The time it takes for ball 1 to slide from H to h is _greater than______ the time it takes ball 2 to fall the same vertical distance.

The time it takes for ball 1 to fall from h to the floor is _less than_____ the time it takes ball 2 to fall from h to the floor.

The velocity of ball 2 when it is at height h is ___equal to____ the velocity of ball 1 when it is also at height h.

The kinetic energy of ball 2 when it is at height h is _equal to______ the kinetic energy of ball 1 when it is also at height h.

The maximum height that ball 2 bounces up from the floor is __less than______ the maximum height that ball 1 bounces in from the floor. (assume no loss in energy).
