Derive an expression for the shear stress at the pipe wall when
an incompressible fluid flows through a pipe under pressure. Use
dimensional analysis with the following significant parameters:
pipe diameter, flow velocity, viscosity and density of the
fluid.
On a friction-free inclined plane, a block glides up the
inclined plane (eventually it will stop and slide down again, but
in this task we look at it as it glides upwards). Which option is
right:
Gravity does a positive job. The normal force does a positive
job.
Gravity does a negative job. The normal force does a positive
job.
Gravity does zero work. Normal force performs zero work.
Gravity does zero work. The normal force does a positive
job....

A 4 kg block is placed at the top of an inclined plane. The
plane is 2.5 meters long and inclined at 34°. The coefficient of
kinetic friction between the block and plane is 0.27. The block
slides the 2.0 meters down the ramp. What speed does it have at the
bottom?
