Two identical carts are released on tracks of equal height as shown. Neglect loss.

- In which case does the cart have a greater initial gravitational potential energy ?

- in which cause does the cart reach the bottom of the track in a shorter time ?

- in which case does the cart have a greater final speed?

Potential answers; Cart A , Cart B, or ‘equal’

Answer 1

cart a and it involves gravitational potential energy

Answer 2

Drop down 1,2, & 3 all are Equal

Step-by-step explanation:

- Both carts have the same initial gravitational potential energy, as they are released from the same height on tracks of equal height.

- Both carts will reach the bottom of the track in the same time, as they are both subject to the same gravitational force and start at the same height.

- Both carts will have the same final speed, as they are both subject to the same gravitational force and experience the same amount of friction over the same distance.
