Question

One car leaves an intersection traveling north at 48 mi/h. Later, a second car leaves that same intersection traveling east at 90 mi/h. At what rate is the distance between the cars increasing when the first car is 96 miles north of the intersection and the second car is 72 miles east of the intersection?

Answer #1

Two cars are approaching an intersection on roads that are
perpendicular to each other. Car A is north of the intersection and
traveling south at 55 mph. Car B is east of the intersection and
traveling west at 50 mph. How fast is the distance between the cars
changing when car A is 20 miles from the intersection and car B is
15 miles from the intersection? (Round your answer to two decimal
places.)
____mph

7. Two cars start moving from the same point. One travels north
at speed of 15 mi/hand the other travels east at 20 mi/h. At what
rate is the distance between the cars increasing two hours
later?

A 1800-kg car approaches an intersection traveling north at 20.0
m/s. A 1600-kg car approaches the same intersection traveling east
at 10.0 m/s. The two cars collide at the intersection and lock
together. Ignoring any external forces that act on the cars during
the collision, what is the velocity of the cars immediately after
the collision?

A 1000-kg car approaches an intersection traveling north at 20.0
m/s.
A car of equal mass approaches the same intersection traveling
east at 22.0 m/s.
The two cars collide at the intersection and lock together.
Ignoring any external forces that act on the cars during the
collision, what is the velocity ,aka, magnitude and direction, of
the cars immediately after collision?

Round your answer to three decimal places. A car is traveling at
144 km/h due south at a point 4 5 kilometer north of an
intersection. A police car is traveling at 128 km/h due west at a
point 2 5 kilometer due east of the same intersection. At that
instant, the radar in the police car measures the rate at which the
distance between the two cars is changing. What does the radar gun
register?

Question 1:
Two cars start moving from the same point. one travels south
at 48 mi/h and the other travels west at 20 mi/h. At what rate is
the distance between the cars increasing two hours later?
Question 2:
A boat is pulled into a dock by a rope attached to the bow of
the boat and passing through a pulley on the dock that is 1 m
higher than the bow of the boat. If the rope is pulled...

Two cars start moving from the same point. One travels south at
56 mi/h and the other travels west at 42 mi/h. At what rate is the
distance between the cars increasing two hours later?
mi/h

Two 200 kg cars approach an intersection. One car is traveling
east at 18 m/s. The second car is traveling north at 24 m/s. They
both collide and violently stick together. Immediately after the
collision they are moving

At time t = 0, a ship leaves point P and heads north at 4 km/h.
One hour later (t = 1) another ship leaves the same point P and
heads east at 6 km/h. How fast is the distance between the ships
increasing at time t = 2?

A 2000-kg car approaches an intersection traveling north
(y-direction) at 12.0 m/s. A 2400-kg car approaches the same
intersection traveling east (x-direction) at 10.0 m/s. The two cars
collide at the intersection and lock together. Ignoring any
external forces that act on the cars during the collision, what is
the speed of the cars immediately after the collision? At what
angle (relative to the x-axis) do the cars travel immediately after
the collision?
At what angle from the x-axis does...
