PLEASE HELP WILL GIVE BRAINLIST IF CORRECT FOR TEST NEED AWNSERS QUICK A roller coaster car of mass m = 200 kg is released from rest at the top of a 60 m high hill (position A), and rolls with negligible friction down the hill, through a circular loop with a height of 40 m (positions B, C, and D), and along a horizontal track (to position E).

1, Write the qualitative conservation equation for the car from point A to point B.

2. What is the velocity of the car at position B?

3.What is the velocity of the car at position D?

please fill out diagram and show work
