Question 1 1 pts Mi A mass M slides upward along a rough plane surface inclined at angle o to the horizontal. Initially the mass has a speed V, before it slides a distance L up the incline. The coefficient of kinetic friction between the mass and the incline is k. While sliding, the acceleration of the mass is: Directed upward along the incline Directed downward along the incline OOOO Determined by the force of gravity on the mass Determined...

Mi A mass M slides-downward along a rough plane surface inclined at angle = 29.21 in degrees relative to the horizontal. Initially the mass has a speed Vo = 7.68 m/s, before it slides a distance L = 1.0 m down the incline. During this sliding, the magnitude of the power associated with the work done by friction is equal to the magnitude of the power associated with the work done by the gravitational force. What is the coefficient of...

A mass m = 15 kg is pulled along a horizontal floor with NO friction for a distance d =7.1 m. Then the mass is pulled up an incline that makes an angle θ = 30° with the horizontal and has a coefficient of kinetic friction μk = 0.38. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 30° (thus on the incline it is parallel...

Two spheres of equal mass M and equal radius R roll down an
inclined plane as shown in the figure. One sphere is solid and the
other is a hollow spherical shell. The plane makes an angle ? with
respect to the horizontal. The spheres are released simultaneously
from rest at the top of the inclined plane and they each roll down
the incline without slipping.
The total distance each sphere rolls down the ramp (the
hypotenuse) is d. There...

A physics student pulls a block of mass m = 22 kg up an incline
at a slow constant velocity for a distance of d = 4.5 m. The
incline makes an angle ? = 32° with the horizontal. The coefficient
of kinetic friction between the block and the inclined plane is µk
= 0.3.
1) What is the work Wm done by the student?
2) At the top of the incline, the string by which she was pulling

Questions 1&2
FP 1. A sliding block of mass m 0.25 kg is subject to a force of magnitude 4 N that makes an angle of ф-30 with the horizontal surface. If the coefficient of kinetic friction between block and surface is 0.5, what is the resulting acceleration of the block along the surface Figure 1: Block on incline. 2. A block of mass m - 5 kg is subject to a force of magnitude 20 N that makes an...

A mass m = 1 kg slides down a θ = 30◦ inclined plane from a
height of 5 m. At the bottom of the incline, it collides with
another mass M = 3 kg, and the latter is initially at rest as shown
in Fig. 3. The surface to the right of the inclined plane on which
the 3 kg (green) mass sits is horizontal.
(a) The inclined surface is frictionless. Conserve energy to
find the velocity of the...
