In a mall, a shopper rides up an escalator between floors. At the top of the escalator, the shopper turns right and walks 11.15 m to a store. The magnitude of the shopper's displacement from the bottom of the escalator to the store is 16.0 m. The vertical distance between the floors is 6.49 m. At what angle is the escalator inclined above the horizontal?

A block is released from rest at the top of an inclined 6.20 m
long. The angle of the incline with respect to the horizontal
direction is and the coefficient of kinetic friction between the
block and the surfaces (incline and horizontal) is . The block
slides along the incline with constant velocity and continues
moving along the horizontal surface until it comes to rest. Using
the work-energy theorem, Determine:
a) The speed reached by the block at the bottom...

Question 1 Figure (a) shows a uniform ramp between two buildings that allows for motion between the buildings due to strong winds. At its left end, it is hinged to the building wall; at its right end, it has a roller that can roll along the building wall. There is no vertical force on the roller from the building, only a horizontal force with magnitude F. The horizontal distance between the buildings is D = 4.00 m. The rise of...

The top edge of a thin rectangular metal plate with a mass of 2.80 kg is attached to a horizontal rod parallel to the edge of the plate. The plate hangs from this rod and is free to rotate about it without friction. The vertical height of the plate is 45.0 cm. The plate is pulled to the right until it makes an angle of 28.0° from vertical and then released from rest. At the same time, a piece of...

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...
