The largest downward force you can exert on a certain
multiple pulley system = 777 N. When you move the rope 3.5 m, the
object moves 0.35 m. What is the heaviest object you could lift?
Could it lift a cow that's 1600 lbs?
In this problem you will determine the amount of force a rider
needs to exert on a bicycle pedal to accelerate at a rate of 1.0
m/s^2.
(c) Now consider the system consisting of the rear wheel. The
system includes the sprocket (gear wheel) attached to it. Assume
that the rear sprocket has a radius of 2.5 cm and neglible mass
compared to the wheel. Assume that the rear wheel has the same
mass, radius, and moment of inertia as...
(a) Two point charges totaling 7.50 µC exert a repulsive force
of 0.150 N on one another when separated by 0.812 m. What is the
charge (in µC) on each? smallest charge in µC largest charge in
µC
(b) What is the charge (in µC) on each if the force is
attractive? smallest charge in µC largest charge in µC
A)Two point charges totaling 8.00 µC exert a repulsive force of
0.100 N on one another when separated by 0.857 m. What is the
charge (in µC) on each? Smallest/Largest? B)What is the charge (in
µC) on each if the force is attractive? Largest/Smallest?
Two point charges totaling 8.5 μC exert a repulsive force of
0.085 N on each other when separated by 0.45 m.
1.) What is the charge on the larger of the two charges in
coulombs?
2.) What is the charge on the smaller of the two charges in
coulombs?
3.) What is the charge in coulombs on the larger
charge (in magnitude) if the force is attractive?
4.) What is the charge in coulombs on the smaller
charge (in magnitude) if the...
Two point charges totaling 9.50 μC exert a repulsive force of
0.160 N on one another when separated by 0.420 m. a) What is the
charge on each? Assume that the two charges are negative. b)What is
the charge on each if the force is attractive?
Two point charges totaling 9.00 µC exert a repulsive force of
0.200 N on one another when separated by 0.712 m.
What is the charge on each if the force is attractive?
How much force could you exert on a large crate if you wanted to
get it moving? One thing the answer depends on is whether you can
keep your footing.
a) Imagine someone on level ground, pushing horizontally against
a crate, with enough effort that their feet are about to start
slipping. Nevertheless, the crate hasn't started moving. What type
of force is the crate exerting on the person pushing on it, and how
does the magnitude of this force...
You
exert a constant force of 20N up the slope on a 20kg block sitting
on a slope of an angle 45 degrees with a coefficient of static
friction of .3 and a coefficient of kinetic friction or .15. Will
the block move? If so, what will it's acceleration be once it's
moving?
A force of magnitude 750.0 N stretches a certain spring by 0.220
m from its equilibrium position. a)What is the force constant of
this spring? b)How much elastic potential energy is stored in the
spring when it is stretched 0.360 m from its equilibrium position.
c)How much elastic potential energy is stored in the spring when it
is compressed by 0.360 m from its equilibrium position? d)How much
work was done in stretching the spring by the original 0.220 m...
