Q1:
In 1967, New Zealander Burt Munro set the world
record for an Indian motorcycle, on the Bonneville Salt
Flats in Utah, of 295.38 km/h . The oneway course was
8.00 km long. Acceleration rates are often described by the
time it takes to reach 96.0 km/h from rest. If this time was
4.00 s and Burt accelerated at this rate until he reached his
maximum speed, how long did it take Burt to complete the
course?
Q2:

on the same track. The engineers see simultaneously that
they are on a collision course and apply the brakes when
they are

apart. Assuming both trains have the same
acceleration, what must this acceleration be if the trains are
to stop just short of colliding?
Q3:
A cyclist in a race has a velocity of 10.2 m/s . The race leader has a velocity of
11.1 m/s . The
cyclist is 2.35 m behind the race
leader when the race leader is
246.5 m from the finish line,
directly ahead. The cyclist begins to accelerate at a rate of
0.422 m/s^{2} . She
continues to accelerate until crossing the finish line,
6.29 s later.
What was the winning cyclist’s final velocity?
How much did the winning cyclist reduce their time by because of accelerating?
What was the difference in finish time between the winner and runnerup?
What was the distance between the runnerup and the winner when the winner crossed the finish line?

Q10:
A care package is dropped out of a cargo plane and lands in a forest.
The impact with trees and snow bring the care package to rest from a downward vertical velocity of
54 m/s .

3.0 m .
What is the package’s average acceleration while it moves this distance?
Assume that downward displacement corresponds to positive values.
Horizontal motion of the package is assumed to be negligible.
