Question

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

Answer #1

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...

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?

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 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...

A 900-kg car traveling east at 15.0 m/s collides with a 750-kg
car traveling north at 20.0 m/s. The cars stick together. What is
the speed of the wreckage just after the collision? In what
direction does the wreckage move just after the collision?

A 940 kg car traveling east at 12.3 m/s collides with a 670 kg
car traveling north at 20.3 m/s . The cars stick together. Assume
that any other unbalanced forces are negligible.
A) In what direction does the wreckage move just after the
collision?
B) What is the speed of the wreckage just after the
collision?

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.

Two cars, both of mass m, collide and stick together. Prior to
the collision, one car had been traveling north at speed 3v, while
the second was traveling at speed 2v at an angle ? south of east
(as indicated in the figure). After the collision, the two-car
system travels at speed vfinal at an angle ? east of north. (Figure
1) Find the speed vfinal of the joined cars after the collision.
Express your answer in terms of v...
