Question

A car moving away from an intersection of two one-way streets at a speed of 15 m/s while a second car approaches the intersection at a speed of 10 m/s. Calculate the rate of change in the distance D between the two cars with time at the instant x = 40 m and y = 30 m.

Answer #1

A 900 kg car moving East with speed of 20 m/s collides with a
1500 kg car moving North with speed of 15 m/s at an intersection.
Both cars stick together after collision. What is the speed and
direction of these two stuck cars immediately after this
collision?

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...

Two identical cars collide at an intersection(m=1500kg). Car 1
is traveling east with a speed of 16 m/s and car 2 is traveling
north with a speed of 12 m/s. Immediately after the collison, car 1
travels with a speed of 8 m/s in a direction 60 north of east. The
cars do not stick together.
(a) What is the speed and direction of travel for car 2 after
the collision? (b) What is the change in kinetic energy of...

Two cars approach an intersection at a right angle to each
other. If an inelastic collision occurs at the
intersection, determine the x component of the final momentum of
the combined vehicles. Car 1 of mass 865 kg approaches
the intersection from the left with a speed of 19.49
m/s. Car 2 of mass 1,121.17 kg approaches the
intersection from the south with a speed of 14.98 m/s.

Two car approach an intersection at a right angle to each
other. If an inelastic collision occurs at the
intersection, determine the x component of the final momentum of
the combined vehicles. Car 1 of mass 882.7 kg approaches
the intersection from the left with a speed of 28.45
m/s. Car 2 of mass 1,778.35 kg approaches the
intersection from the south with a speed of 10.68 m/s.

Two cars collide at an icy intersection and stick together
afterward. The first car has a mass of 1100 kg and is approaching
at 9.5 m/s due south. The second car has a mass of 950 kg and is
approaching at 15 m/s due west.
Part (a) Calculate the magnitude of the final
velocity, in meters per second, of the cars.
Part (b) Calculate the direction of the final
velocity, in degrees south of west, of the cars.
Part (c)...

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

Two cars approach an ice-covered intersection. One car, of mass
1.21 X 10^3 kg, is initially traveling north at 12.1 m/s. The other
car, of mass 1.62 X 10^3 kg, is initially traveling east at 12.1
m/s. The cars reach the intersection at the same instant, collide,
and move off coupled together. Find the velocity of the center of
mass of the two-car system just after the collision.
magnitude: ______
direction: _____ north of east

A car with a mass of 1,400 kg and a speed of 15 m/s heading
north approaches an intersection. At the same time, a minivan with
a mass of 1,800 kg and speed of 22 m/s heading east is also
approaching the intersection. The car and the minivan collide and
stick together. What is the velocity of the wrecked
vehicles just after the collision? Ignore friction between
the tires and the surface of the road. (Enter the magnitude
in m/s...

Car
A has a mass of 2000 kg and approaches an intersection with a
velocity of 38 m/s directed to the east. Car B has a mass of 3500
kg and approaches the intersection with a velocity of 53 m/s
directed 63° north of east. The two cars collide and stick together
after the collision. Calculate the velocity after the
collision.
