A car going at 24 ft/s decelerates at a constant 4ft/s^2 to cometo a stop.
a) Fill in the following table showing the velocity of the carevery second. Fill in a zero velocity for any time after that atwhich the car comes to a rest.
t = 0 1 2 3 4 5 6 7
v = 24 20 16 12 8 4 0 0
b) When does the car come to a stop?
at t = _6_
Using your table, find left and right sums which estimate thetotal distance traveled before the car comes to rest. Which is anoverestimate, and which is an underestimate?
The right sum is an underestimate, and is = 60
The left sum is an overestimate, and is = 84
c) On a sheet of paper, sketch a graph of velocity against time.On the graph, show an area representing the distance traveledbefore the car comes to rest. Use the graph to calculate thisdistance.
distance = _?_
d) Now find a formula for the velocity of the car as a functionof time:
velocity = _?_
and then find the total distance traveled byantidifferentiation.
distance = _?_
