Question

2) A roller coaster cart initially moving with a velocity of 80 m/s begins to

slow down as it approaches the end of the track to a final speed of 5.0 m/s
in 25 sec. Calculate the acceleration of the roller coaster cart during the
25 second period:

Answer 1

-3 m/s^2

Step-by-step explanation:

Acceleration = change in velocity / change in time

= - 75 m/s / 25 sec = - 3 m/s^2
