Your vertical spring accelerometer has a 200 g mass hanging from it. You climb aboard the roller coaster and watch the accelerometer read 0.4 g for 3 seconds while descending the first peak and then change to 1.5 g for 2 seconds while climbing the second peak. Your fully loaded car is 2000 kg.
a. What is your acceleration going down, and what is it going up in m/s^2?
b. Calculate your final velocity going down and going up.

How would I go about solving this? Thank you ~
