Question

A roller coasters velocity at the top of the hill is 10 m/s. Two seconds later it reaches thebottom of the hill with a velocity of 26m/s. What is the acceleration of the coaster?A.13 m/s/s
B.4 m/s/s
C.2.6 m/s/s
D.8 m/s/s

Answer 1

Answer:

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s. There are slight variations in this numerical value (to the second decimal place) that are dependent primarily upon on altitude.
