Question

Car A has a positive velocity v(t) as it travels along a straight road, where v is a differentiable function of t. The velocity of the car is recorded for several selected values of t over the interval 0<=t<=60 seconds, as shown in the table below

t (seconds): 0 10 20 30 40 50 60
v(t) (rate)   : 5 14 7   11 12 40 44

Use the data from the table to approximate the acceleration of Car A at t = 25 seconds
Show the computation that leads to the answer please.

a=du/dt =>a = uf-ui/tf-ti ==>a=30-20/11-7 in m/s^2
