A large crate with mass m rests on a horizontal floor.
The static and kinetic coefficients of friction between the crate
and the floor are μs and μk, respectively. A
woman pushes downward on the crate at an angle θ below the
horizontal with a force F⃗ .
What is the magnitude of the force vector

constant velocity?
If μs is greater than some critical value, the woman
cannot start the crate moving...

A block rests on a horizontal, frictionless surface. A string is
attached to the block, and is pulled with a force of 48.0 N at an
angle θ above the horizontal. After the block is pulled through a
distance of 16.0 m its speed is v = 2.10 m/s, and 40.0 J
of work has been done on it.What is the mass of the block? (Answer
in kg)

A block with a mass of 2.5kg lies on a surface that is inclined

An 8.5-kg block is pushed along a horizontal rough surface by a
40-N force inclined at 20° with the horizontal. The coefficient of
friction between the surface and block is 0.35. If the block has an
initial velocity of 3.6 m/s and the force does 200 J of work on the
block, find:

(b) The final velocity of the block.

A block of mass m = 3.3 kg is on an inclined plane with
a coefficient of friction μ1 = 0.39, at an
initial height h = 0.53 m above the ground. The plane is
inclined at an angle θ = 44°. The block is then compressed

equilibrium point (the spring has a spring constant of
k1 = 35 N/m) and released. At the bottom of the
inclined plane...
