a. What is the acceleration at:
i.
t = 11 s?
ii.
t = 15 s?
b. How far, and in which direction, did the object travel:
i.
from t = 4 to t = 11 s?

ii.
from t = 13 tot = 18 s?
c. During what time intervals is the object speeding up?
slowing down?
d. During what time intervals is the acceleration positive?
Negative? Zero?
Velocity (m/s)
a. The position of an object is given by x(t) = A + B*t + C*t³ (yes, those exponents are intentional, this is
NOT constant acceleration). Provided that x is measured in meters and t in seconds, what must be the
units for the constants A, B, and C.
b. Another position function is given by y(t) = D # E*t1 + F*t3/2). What are its velocity, and acceleration
functions with time?
c. Bonus: choose and declare your values for D, E and F, and make graphs of y(t), vy(t), and a,(t). Don't
forget appropriate units at each step.
The Nardo ring is a circular test track for cars. It has a circumference of 12.5 km. cars travel around the track at a constant speed of 100 km/h. A car starts at the easternmost point of the ring and drives for 15 minutes at this speed.
a. What distance, in km, does the car travel?
