Energy Scramble: Solving Physics Problems
What do these words have in common?
Energy Scramble
For each of the problems, solve for the desired variable. There
will only be 4 unique answers across all 15 problems. DO NOT
ROUND until the very end.
For all problems that have the same answer related by factors of
10, unscramble the letters to form a word.
A car covers a distance of
100 m in 9.231 s. The thrust
of the engine is 1,500 N.
What is the power of the
car?
Power Output
A
A block of mass 6 kg is
moving at 4 m/s across a
rough, horizontal surface.
A constant frictional force
acts on the block bringing
it to rest over a distance of
6.51 m. What is the
coefficient of friction on
the block?
Coefficient of
Friction

at 2.5 m/s
2
for 167.2 meters. What
is its final kinetic energy?
Kinetic Energy
D

vertical ladder 2.238m tall in a time
of 8.0s. What is the power output
in horsepower? (1 hp = 746 W)
Horsepower
E
I launch a 0.25 kg ball
bearing from a spring
launcher with a spring
constant of 6359.2 N/m. If
the exit velocity of the ball
is 20 m/s, how far did I
compress the spring?
Spring
Compression
E
A rock of mass 3 kg is dropped from
the top of a building 35 m tall. As it
falls, it experiences air resistance.
Right before impact, the rock is
traveling at a speed of 23.0575 m/s.
What is the percentage of energy
lost due to air resistance?
% Heat Loss
G
A car of mass 1200 kg,
accelerates from 10 m/s to 30
m/s. It travels a distance of
382.775 m during this process.
What is the average force that
car feels from the engine
during this time?
Force
J
A bungee jumper (m=85 kg) starts
80 m above the ground and jumps
off. She falls until stopped 20 m
above the ground. The bungee cord
is originally 52.157 m long before
being stretched out. What is the
spring constant of the bungee cord?
Spring Constant
L
A 15.625-kg cannon ball is launched
upwards at 15 m/s. How much
kinetic energy does it have 10
meters above its launch height?
(Assume no air resistance and
use g = 9.81 m/s

)
Kinetic Energy
M
A bird of mass 15 kg is flying at
a speed of 25 m/s at a height
of 78.6565 m above the
ground. What is the total
energy of the bird?
Total Energy
O
A car smashes into a crash barrier
and imparts a constant force of
40,625 N while it compresses from
4.7 m to 4.3 m. How much energy
was dissipated?
Work-Energy
P
Final velocity
A 75-kg cliff diver is 25 meters above
the surface of the water. What is the
speed of the diver at the bottom if
she loses 71.7184% of her energy to
air resistance?
R
Mass
An elevator is being lifted up by an
engine putting out a power of
20,000 W. The elevator raises a
distance of 20 m in 6.05366
seconds. The elevator is 500 kg by
itself and contains 2 people on this
trip. How much is the combined
mass of both people?
U
What is the elastic potential energy
stored in a giant slingshot ride with a
spring constant of 163.5 N/m when
stretched back from its resting length of
5 m to a stretched length of 17 m?
Elastic Potential
