Question

t(s)    0      1.0     2.0      3.0       4.0         5.0
x(m) 0      2.3      9.2     20.7     36.8       57.5

(a) Use the data to construct a smooth graph of position versustime. (b) By constructing tangents to the x(t) curve, find theinstantaneous velocity of the car at several instants. (c) Plot theinstantaneous velocity versus time and, from the graph, determinethe average acceleration of the car. (d) What was the initialvelocity of the car?

for (b) can you explain briefly how you'd get the instantaneousvelocity? thanks
