1. A mass of 9.9 kg is resting on a horizontal surface without
friction. A force is applied vertically upward to the mass. What
does the amount of this force need to be in order to begin to pull
the mass off the surface, in Newtons?
2. A mass of 8 kg is resting on a horizontal surface without
friction. A force of 143 Newtons is applied in the +x direction, a
force of 19 Newtons is applied in the...

A 20.4 kg iron mass rests on the bottom of a pool. (The density
of iron is 7.86 ✕ 103 kg/m3 and the density of water is 1.00 ✕ 103
kg/m3.)

Block A, mass 5.00 kg, rests on a surface with μk = 0.600. A
massless rope is attached to its right side, and runs over a
pulley, treated as a thin ring, mass 1.00 kg and radius 5.00 cm, to
Block B, mass 7.00 kg, which hangs from the rope and is held at
rest. The rope does not slip over the pulley, and the pulley spins
on a frictionless axle. Block B is released from rest, and after an...

a) A block with a mass of 0.600 kg is connected to a spring,
displaced in the positive direction a distance of 50.0 cm from
equilibrium, and released from rest at t = 0. The block then
oscillates without friction on a horizontal surface. After being
released, the first time the block is a distance of 15.0 cm from
equilibrium is at t = 0.200 s.
What is the block's period of oscillation?
_______ s
b) A block with a...

A mass m1 = 5.2 kg rests on a frictionless table and connected
by a massless string to another mass m2 = 5.2 kg. A force of
magnitude F = 38 N pulls m1 to the left a distance d = 0.83 m.
1) How much work is done by the force F on the two block
system?
2) How much work is done by the normal force on m1 and m2?
3) What is the final speed of the...

A 20.2 kg copper mass rests on the bottom of a pool. (The
density of copper is 8.92 ✕ 103 kg/m3 and the density of water is
1.00 ✕ 103 kg/m3.) HINT Archimedes' principle states, "Any object
completely or partially submerged in a fluid is buoyed up by a
force with magnitude equal to the weight of the fluid displaced by
the object." Click the hint button again to remove this hint. (a)
What is the volume of the copper...

Block 1 (5 kg) is located on the surface of a table. A hand
pushes horizontally to the right on block 1 with a normal force of
85 N. The coefficient of kinetic friction between the block and the
surface equals 0.8. On a sheet of paper, draw the free body diagram
for block 1 using the two-subscript notation from class. After
completing the free body diagram, enter below each force and its x
& y-components. Remember that the x-component...

A 1 kg mass is on a horizontal frictionless surface and is
attached to a horizontal spring with a spring constant of 144 N/m.
The spring's unstretched length is 20 cm. You pull on the mass and
stretch the spring 5 cm and release it. The period of its
oscillations is T=.524s The amplitude of the block's oscillatory
motion is 5cm The maximum velocity of the oscillating mass is
60cm/s Part E) While the frictionless surface is working well, the...

A 20.0 kg box (200 N) rests on an incline. The surface makes an
angle of 22.62° with the horizontal and has µk = 0.62 and µs =
0.81.
A) A horizontal force with a magnitude of 400 N acts on the box.
Does the box move? If not, why not? If it does, what is its
acceleration
B) What minimum horizontal force is required to keep the box
from sliding down the incline?
