Question

78) A quarter with a diameter of 2.5cm, a width of 0.2cm, and a
mass of 5.7g rests at the bottom of a 2.5-m deep

pool. (a) Draw a force diagram showing all of the forces being
exerted on the quarter and (b) determine the

magnitudes of all forces exerted on the quarter.

Answer #1

(Show all steps please) there is no mass for the box
Equilibrium: A plank, 40 m long rests on two pylons positioned
at each end. The plank is inclined at 10 degrees with the left side
higher than the right side. The plank is 40 kg. A box rests at a
point 5 m from the left side.
A) Draw a free body diagram of the system.
B) Write down an expression for calculating the torque that
includes force, the...

61) The position of a 0.75-kg cart attached to a spring can be
given by the equation . (a) Plot position-time,
velocity-time, and acceleration-time graphs representing the motion
of the cart. (b) Draw a force diagram showing all forces exerted on
the cart when it is at its maximum displacement away from
equilibrium. (c) Determine the force the spring exerts on the cart
at that displacement.
no
equation was given, sorry :(

A box with mass m = 1.2kg on an inclined frictionless surface is
released from rest from a height h = 1.35 m . After
reaching the bottom of the incline the box slides with friction
(μk=0.2) along a horizontal surface until coming to a rest after a
distance d.
1. Draw a free body diagram for the box while it is on the
incline. Clearly label all forces with standard names.
2. Draw a free body diagram for the...

A box, initially at rest, is pulled by a rope as it slides along
a horizontal (level) carpeted floor in the positive direction;
there is friction. The mass of the box is 8 kg and the tension in
the rope has a magnitude of 40 N. After 4 seconds of pulling, the
box has a speed of 12 m/s.
1. While the box is being pulled:
a. what is the magnitude of acceleration of the box? Answer:
_________
b. what...

A proton, with mass 1.67 × 10-27 kg and charge +1.6 × 10-19 C,
is sent with velocity 7.1 × 104 m/s in the +x direction into a
region where there is a uniform electric field of magnitude 730 V/m
in the +y direction. What are the magnitude and direction of the
uniform magnetic field in the region, if the proton is to pass
through undeflected? Assume that the magnetic field has no
x-component and neglect gravitational effects.
Draw a...

A uniform thin rod of mass m = 2.9 kg and
length L = 1.9 m can rotate about an axle through its
center. Four forces are acting on it as shown in the figure. Their
magnitudes are F1 = 5.5 N,
F2 = 2.5 N, F3 = 11 N and
F4 = 19.5 N. F2 acts a
distance d = 0.23 m from the center of mass.
A) Calculate the magnitude τ1...

1. A bottle of mass 0.5 kg is given an initial velocity of 2.3
m/s on a rough, horizontal surface. Draw a diagram showing all of
the forces on the bottle as it moves across the surface. The bottle
comes to rest after travelling a distance of 1.3 m. Calculate the
time taken to come to rest, the deceleration and the friction
force.
2. Block A has a mass of 4 kg and block B has a mass of 6...

Problem 1: An air-boat.
Rangers at the everglades national park, ride an air-boat, the
mass of the air boat plus the rangers is 500 kg. The blades of the
boat push on the air with 1000N, while moving the rangers
experience an air resistance force of 200N directed opposite to the
direction of motion, and the boat a water resistance of 250N. They
move in straight line for 20s. Please complete the following
tasks:
Draw the free-body diagram showing all...

Question 20: A pirate has left his treasure chest sitting on a
hillside (inclined plane), where the static friction prevents it
from sliding down. The treasure chest has mass m, and the incline
makes an angle theta with the horizontal. a) (3 points) Draw the
free-body diagram for the treasure chest sitting on the hillside.
Label all forces, and make sure that directions and magnitudes are
correct, to reasonable accuracy. Draw the coordinate system that
you want to use, too....
