Complete the following exam questions:
Q1. The graph represents the motion of a cyclist at the start
of an Olympic race.
(i) Calculate
the initial acceleration.
(2)
acceleration =
........................................................... m/s2
(ii) Another cyclist has a smaller initial acceleration but then reaches a constant velocity of 17 m/s.
Copy the graph and draw her motion on the graph.
(1)
(iii) The cyclists have to keep pedalling to maintain their constant velocity.
Give one reason why they have to keep pedalling to maintain
their constant velocity.
(1)
(iv) One
cyclist produces an average power output of 600 W during the race.
She completes the race in exactly 4 minutes.
Calculate the work done by the cyclist during the race.
(3)
work done = ...........................................................

Q2. A 60 kg student weighs 600 N. He does a bungee jump.
The bungee cord becomes straight and starts to stretch when
he has fallen 50 m.
(a) Complete the sentence by putting a cross ( 
) in
the box next to your answer.
) in
the box next to your answer.
He first stops moving
(1)
A before all
the energy has disappeared B before the
bungee cord starts to stretch C when the
bungee cord is stretched the most D when the
elastic potential energy is zero
(b) Complete the sentence by putting a cross ( ) in
the box next to your answer.
) in
the box next to your answer.
When his speed is 10 m/s his
momentum is
(1)
A 600 kg m/s B 3 000 kg m/s C 6 000 N m/s D 30 000 N m/s
(c) (i) Calculate the change in gravitational potential
energy as the student falls 50 m.
Give the unit.
(3)
(ii) State at what point in the bungee
jump the student has maximum kinetic energy.
(1)
(iii) Explain why his maximum kinetic
energy is likely to be less than your answer to (c)(i).
(2)
Due 13/1/20
Complete the following 6 mark question in your exercise book:
Fuels in gas fires contain methane.
The complete combustion of methane
produces carbon dioxide and water. In faulty gas fires, incomplete combustion
of methane can take place.
Discuss the problems that can be caused
by both the complete and incomplete combustion of methane in a gas fire. (6)
