Question

a 2000 kg car moving down a 30°incline. A counterweight of mass 180 kg on a 20°inclinehelps control the car’s speed, as well as the brakes of the car. Ignore friction and assume the car goes down

a)Draw an FBD of both the car and the counterweight.

b)Write down N II equations.c)Find the braking force necessary for the car to move down the hill at a constant speed.

Answer #1

Please let me know if it was helpful. Thank you!

The 2040 kg cable car shown in the figure descends a 200-m-high
hill. In addition to its brakes, the cable car controls its speed
by pulling an 1860 kg counterweight up the other side of the hill.
The rolling friction of both the cable car and the counterweight
are negligible.
Part A: How much braking force does the cable car need to
descend at constant speed?
Part B: One day the brakes fail just as the cable car leaves the...

A 1900-kg car experiences a combined force of air resistance and
friction that has the same magnitude whether the car goes up or
down a hill at 27 m/s. Going up a hill, the car’s engine produces
35.10 kW more power to sustain the constant velocity than it does
going down the same hill. Calculate at what angle the hill is
inclined above the horizontal.

A 2000 kg car starts from rest. After 2 seconds, the car is
moving at a velocity of 9 m/s. There is a retarding friction force
of 600N acting on the car. What is the power needed by the car in
order to accelerate from rest to that final velocity?

A BMW of mass 2000 kg is traveling at 42 m/s. It approaches a
1000 kg Volkswagen going 25 m/s in the same direction and strikes
it in the rear. Neither driver applies the brakes. Ignore the
relatively small force on the cars due to the road and due to air
resistance. (a) If the collision slows the BMW down to 33 m/s, what
is the speed of the VW after the collision? (b) During the
collision, which car exerts...

A 3.0 kg block slides down an incline that makes an angle ? =
30?The coefficient of kinetic friction between the block and the
incline is ?k = 0.3 If the incline is 3 m long:
1. Determine the work done by friction
2. Determine the work done by the normal force
3. Determine the work done by gravity
4. What is the total work done on the block?
5. If the block is given an initial speed of 5...

A race-car driver is driving her car at a record-breaking speed
of 225 km/h. The first turn on the course is banked at 15, and the
car’s mass is 1450 kg.
find :
a) Calculate the radius
of curvature for this turn.
b) Calculate the
centripetal acceleration of the car.
c) If the car
maintains a circular track around the curve (does not move up or
down the bank), what is the magnitude of the force of static
friction?...

Traveling at 40.2 m/s, a driver applies the brakes to his
fast-moving car and skids out of control on a wet concrete
horizontal road. The 2000 kg car is headed directly toward a
student waiting to catch a bus to campus who is standing 58.0 m
down the road. Luckily, Superman is flying overhead and surveys the
situation. Knowing that the coefficient of kinetic friction between
rubber and rough wet concrete is .800, he determines that friction
alone will not...

A 3.00 kg block starts from rest at the top of a 30° incline and
accelerates uniformly down the incline, moving 1.83 m in 1.80
s.
(a) Find the magnitude of the acceleration of the block.
m/s2
(b) Find the coefficient of kinetic friction between the block
and the incline.
(c) Find the magnitude of the frictional force acting on the
block. N
(d) Find the speed of the block after it has slid a distance
1.83 m. m/s

Bob is driving his car at 20 m/s down a hill
with a slope of 5 degrees. When a deer suddenly jumps out of the
woods onto the road, he slams on the brakes, and the car skids to a
stop. The mass of the car is 1500 kg, and the coeﬃcient of kinetic
friction between the tires and the road is µk = 0.816.
a) (3 points) Draw a free-body diagram for the car.
b) (3 points) Determine the...

1. A 1,761-kg car is moving down a road with a slope (grade) of
12% at a constant speed of 17 m/s. What is the direction and
magnitude of the frictional force? (define positive in the forward
direction, i.e., down the slope)?
2. A 1,892-kg car is moving down a road with a slope (grade) of
12% while slowing down at a rate of 3.7 m/s^2. What is the
direction and magnitude of the frictional force? (define positive
in the...
