Question
it is not equal, cannot tell, greater than, less than,or equal to• The time it takes from block 1 to slide from H to his ....................... the time it takesblock 2 to fall the same vertical distance.
• The velocity of block 1 when it is at height his ...................... the velocity of block2 when it is also at height h.
• The change in potential energy of block 1 when it slidesfrom H to h is ............... the change inpotential energy of block 2 when it falls from H to h.
• The time it takes from block 2 to fall from h to the flooris ................ the time it takes block 1 to fallfrom h to the floor.
• The kinetic energy of block 2 when it is at height his............ the kinetic energy of block 1 when it is alsoat height h.
Explanation / Answer
The time it takes from block 1 to slide from H to h is greaterthan the time it takes block 2 to fall the samevertical distance. The velocity of block 1 when it is at height his equal the velocity of block 2 when it is alsoat height h. The change in potential energy of block 1 when it slides from H toh is equal the change in potential energy of block2 when it falls from H to h. The time it takes from block 2 to fall from h to the flooris less than time it takes block 1 to fall from h to thefloor. The kinetic energy of block 2 when it is at height h is equalto the kinetic energy of block 1 when it is also at height h.
