Acceleration = (change in speed) / (time for the change)
change in speed = (20-120)= -100 m/s.
1.5 min = 90 sec
acceleration = -100/90 = -1.11 m/s^2.
We don't care about the 150kg or the 2,500 meters. They don't make any difference.
Given:
Loaned amount: 450
Payment: 543.75
Term: one month
543.75 - 450 = 93.75 interest for 1 month.
93.75/450 = 0.2083 or 20.83% monthly interest.
0.2083 x 12 months = 2.50 or 250%
The monthly interest rate is 20.83% and its associated APR is 250%.
