A person takes a trip, driving with a constant speed of
94.5k(m)/(h)
, except for a
22.0-min
rest stop. If the person's average speed is
75.8k(m)/(h)
, find the A race car moves such that its position fits the relationship
x=(4.0(m)/(s))t+(0.70(m)/(s^(3)))t^(3)
where
x
is measured in meters and
t
in seconds. (a) A plot of the car's position versus time is which of the following?following. (a) How much time is spent on the trip? h (b) How far does the person travel? km
