⩥ A ball is dropped from rest and falls to the floor. the initial
gravitational potential energy of the ball earth system is 10 J. the ball
then bounces back up to a height where the gravitational potential
energy is 7 J what was the mechanical energy of the ball earth floor
system the instant the ball hit the floor? Answer: C. 7 J
⩥ The pendulum shown in the figure above reaches a maximum height
H above the equilibrium position as it also leads assuming friction air
assistants are negligible which of the following is true about the total
energy of the earth pendulum system as the pendulum oscillates Answer:
C. It is constant throughout the pendulum's motion
⩥ an athlete with mass m running at speed V grabs a light rope that
hangs from ceiling of height H and swings to a maximum of each one in
another room with the lower ceiling of height H/2, a second athlete with
mass 2m running at the same speed V grabs a light rope hanging from
the ceiling and swings to a max height of h2. How does the max height
reached by the two athletes compare, and why? Answer: D. The two
athletes reach the same height, b/c the athletes run with the same speed.
⩥ which block takes the longest time to reach the ground?? Answer: B. b
, ⩥ Which block has the greatest speed just before hitting the ground?
Answer: D. the blocks reach the ground with the same speed
⩥ A student was asked to determine the work done on a block of wood
when the block is a pulled horizontally using an attached string. The
student is supplied with the spring scale, stopwatch, and a meter stick.
which of the following graphical analysis techniques will allow the
student to the sermon the work done on the block by the string? Answer:
A. graphing the force as a function of time and calculating the slope
⩥ some students want to talk to leave the work done by friction as an
object with a unknown mass moves along a straight line on a rough
horizontal surface. the students have a force probe, meter stick, and a
stopwatch. which of the following will allow the students to take
measurements needed to calculate the work done by friction? Answer: B.
pulling the block at an unknown constant speed with the force probe for
a measured time
⩥ A block of mass 10kg moves from position A to position B shown in
the figure above. The speed of the block 10m/s at A and 4.0 m/s at B. the
work done by friction on the block as it moves from A to B is most
nearly. Answer: -220 J
⩥ A person holds a book at rest a few feet above a table. the person then
lowers the book at a slow constant speed and places it on the table.
