Question

3. If the mass of the cart is 10 g (1 kg = 1000 g), how much
is the initial height in position 1? (v=0, Ug=0.100J, Ek=0J,
Etot=0.100J)

4. If the mass of the cart is 10 g (1 kg = 1000 g), how much
is the normal force on the cart in position 3? (r=0.500m,
Ek=0.040J, Ug=0.040J, Etot=0.100J)

Answer #1

I had a lab where we had to find the frictional force of a
system. A cart was let go at the top of a 15 degree incline and the
time it took the cart to reach the bottom of the incline was
measured. I need to find the change in energy of the system. The
distance is 90cm. The velocity of the cart was 0.517 m/s. The force
it took for the cart to go up was 2.08 N...

The combination of an applied force and a frictional force
produces a constant torque of 40 N·m on a wheel rotating about a
fixed axis. The applied force acts for 8.0 seconds, during which
time the angular speed of the wheel increases from 0 to 700
degrees/second. The applied force is then removed, and the wheel
comes to rest in 55 s. Answer the following questions. (a)What is
the magnitude of the angular acceleration of the wheel while the
applied...

An elevator car has a mass of 1500 kg carry 3
passengers with a total mass of 330 kg. The lift operates
with a constant frictional force of 2 700 N working
against the motion of the elevator.
How much power must the motor deliver to the elevator cart to
keep it moving at a constant speed of 2.4
ms-1 ?
How much power would need to be supplied by the motor if it was
70% efficient?

A 2 kg mass is connected to a wall through a spring with force
constant of 8 N/m. Using the Laplace transform method, calculate
the time-dependent position of the mass, x(t) for t > 0, for the
following cases:
The mass is initially at rest, and then is hit at time zero with
an impact described by f(t) = delta function.
The mass is initially at rest, and then is hit at time t = 1 s
with an impact...

6) A mass of 3 kg is attached to a massless spring with
a force constant 500 N/m. The mass rests on a horizontal
frictionless surface. The system is compressed a distance of 30 cm
from the springs initial position and then released. The momentum
of the mass when the spring passes its equilibrium position
is?
8660.25m/s
Is this right

11.2 A mass oscillates on a spring of force constant 25.0 N/m
and is subjected to a damping force Fx = ?bvx , where b = 2.40
kg/s. (a) What special value of the mass m determines whether the
mass undergoes underdamped oscillations, is critically damped, or
is overdamped? (b) If m is eight times this special value, how long
does it take for the amplitude to be reduced by 50%? What is the
period of the oscillation? Plot the...

What is the magnitude of the force exerted by a spring with a
spring constant of 447N/m, if it is stretched by 77cm?
You attach a 46.8g weight to a vertical spring and let it slowly
move down until it is in equilibrium. By how much, measured in cm,
the spring is stretched at equilibrium if the spring constant is
24N/m? g=9.8m/ s2
What is the period of the oscillations of a mass-spring system,
measured in seconds, if the mass...

A particle with mass m=1 kg is thrown vertically upward in a
constant gravitational field with an initial speed of
v0=8 m/s. There is a retarding force F = - k m
v2 acting on the particle where v is the instantaneous
speed and k=1.5 (in SI units). The speed of the particle when it
returns to the initial position is

A ball with mass m = 50.0 g, is sitting on a vertical
spring whose force constant is 120.0 N/m. The initial position of
the spring is at y = 0.00 m.
The spring is compressed downward a distance x = 0.200
m. From the compressed position, how high will the ball bearing
rise? How high is does the ball bearing rise above the position at
y = 0.00 m?
What is the kinetic energy of the ball at the...

TMU #17. ex.1
In an experiment where a 0.50- kg ball rolls down and up two
inclined planes from an initial height of 1.0 m, the final change
in the average energy per atom in the system is estimated to be 4.9
x 10-26 J. as the number of atoms and molecules in the
system was considered to be be 1026 . By the end of the
experiment, everything in the system is slightly warmer. How much
warmer?
