Question

Consider a car driving due north. The direction of the angular momentum of the car's wheels is?

Answer #1

On a moving bicycle, the angular momentum of the spinning wheels
is directed to the rider’s left. If the bike is ridden “no handed”,
what is the effect of the rider leaning to the left? That is, does
the bike go left, go right, or continue straight ahead?
Explain.

Consider your Hummer from before, driving at a speed of v =
60mph. Your wheels have the speciﬁcation 38×14.00R22LT which we
here assume to translate into a diameter of d = 1m for simplicity.
What is the corresponding angular velocity ω? From your position at
which you decide to hit your neighbor’s parked car to the actual
point of impact a time of t = 5s elapses. How many turns do your
wheels make during this time interval? At what...

The car's wheelbase (the distance between the wheels) is 8 feet.
The weight of the car including passengers is 3000 pounds and its
weight acts at a point x = 6 feet and y = 2 feet from the rear
wheel touching the ground.. Set the point the back wheels touch the
ground as (0,0,0) If the angle alpha to the road is equal to 30
degrees answer the below questions. car Let NR be the force in
pounds on...

A car has a mass of 1000kg. The car is moving at 20.00m/s due
North. A small explosion inside the car splits it into two perfect
equal mass pieces each moving North. The back half of the car is at
rest after the explosion. What is the momentum of the front half of
the car immediately after the explosion?
A. 10,000kg m/s
B. Can't be determined
C. Zero
D. 14,142 kg m/s
E 20,000 kg m/s

A 1000-kg sports car is moving north at speed 15 m/s on a level
road when it collides with a 2000-kg truck driving east on the same
road at speed 10 m/s. The two vehicles remain locked moving
together after the collision at the origin of x-y plane. Assume
that the rolling friction is too small to be ignored.
A) explain what type of collision it is
B) indicate the vector momentum by showing its magnitude and the
(direction) angle...

three 1500 kg cars are driving at 25m/s along the road. Car A is
on a flat portion of the road, car B is at the bottom of a hill and
car C is at the top of a hill. (a)Determine the normal force that
the road exerts on each car. Suppose each car suddenly brakes hard
and starts to skid. (b) Determine the magnitude and direction of
each car's acceleration. The coefficient of kinetic friction
between the tires and...

A police car is traveling at a velocity of 17.0 m/s due north,
when a car zooms by at a constant velocity of 44.0 m/s due north.
After a reaction time 0.500 s the policeman begins to pursue the
speeder with an acceleration of 6.00 m/s^2. Including the reaction
time, how long does it take for the police car to catch up with the
speeder?

A police car is traveling at a velocity of 19.0 m/s due north,
when a car zooms by at a constant velocity of 42.0 m/s due north.
After a reaction time 0.500 s the policeman begins to pursue the
speeder with an acceleration of 5.00 m/s^2. Including the reaction
time, how long does it take for the police car to catch up with the
speeder?

Consider a proton in an MRI machine with an angular momentum
aligned with the Z axis. The MRI machine applies a torque about the
+X axis.
After one quarter of the precession period, along which axis
does the angular momentum point ?
A. Along the +x axis
B. Along the –x axis
C. Along the +y axis
D. Along the –y axis
E. Along the +z axis

1. A car is driving northwest at vv mph across a sloping plain
whose height, in feet above sea level, at a point NN miles north
and EE miles east of a city is given by
h(N,E)=3250+125N+75E.h(N,E)=3250+125N+75E.
(a) At what rate is the height above sea level
changing with respect to distance in the direction the car is
driving?
(b) Express the rate of change of the height of
the car with respect to time in terms of vv.
