Question

At the instant shown, the car at A is traveling 10 m/s at 45° SE around the curve with radius of curvature of 100 m, while increasing its speed at 8 m/s sq. The car at B is traveling at 18.5 m/s along the straightway eastward and increasing its speed at 5 m/s sq. Determine the relative velocity and relative acceleration of B with respect to A at this instant. The normal component of acceleration for car A makes a 45° with the horizontal axis at the center of curvature. Show the proper units in all cases.

1.Determine the relative velocity, in vector form, of B with respect to A

2.Determine the direction (angle and sense) of the relative velocity of B with respect to A. Indicate the sense as SW (southwesterly), SE (southeasterly), NW (northwesterly) or NE (northeasterly).

Answer #1

At the instant shown, the car at A is traveling 10 m/s at
45° SE around the curve with radius of curvature of 100
m, while increasing its speed at 8 m/s sq. The car at B
is traveling at 18.5 m/s along the straightway eastward and
increasing its speed at 5 m/s sq. Determine the relative
velocity and relative acceleration of B with respect to A at this
instant. The normal component of acceleration for car A makes a
45° with...

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?

During a parasailing ride, the boat is traveling at a constant
38 km/hr with a 200-m long tow line. At the instant shown, the
angle between the line and the water is 30º and is increasing at a
constant rate of 2º/s. Determine the velocity and acceleration of
the parasailer at this instant.(Round the velocity and acceleration
to three decimal places and the angles to one decimal place.)
The velocity of the parasailer and angle
The acceleration of the parasailer...

A car is traveling along a straight road at a velocity of +35.0
m/s when its engine cuts out. For the next ten seconds the car
slows down, and its average acceleration is a1. For the next five
seconds the car slows down further, and its average acceleration is
a2. The velocity of the car at the end of the fifteen-second period
is +24.2 m/s. The ratio of the average acceleration values is a1/a2
= 1.78. Find the velocity of...
