11,250 J
750 J
22,500 J
45,000 J
Which of the following statement is correct regarding the mechanical energy of the system?
The roller coaster has more mechanical energy at point C than point B because it has more KE at point C.
The roller coaster has less mechanical energy at point C than point B because it has less PE at point C.
The roller coaster has more mechanical energy at point A than point C more potential energy at point C.
The roller coasters mechanical energy is the same at all location because ME is the sum of PE and KE.
Which object from the table has the LEAST momentum?
Object A
Object B
Object C
