Question

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?

Answer #1

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 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...

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 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 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 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...

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 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 car (m1=2000kg) is traveling east with a velocity of 20i m/s.
this car collieds with a second car (m2=1500kg) that is traveling
north with a velocity 20j m/s. these 2 cars tangle together when
they collide.
what was the total kinetic energy before the collision?
what is the magnitude of the momentum of the 2 cars (as 1
system)?
what is the speed of the combined mass just after the
collision?
what is the direction traveled in degrees?

Consider the collision of a 1500-kg car traveling east at 20.0
m/s (44.7 mph) with a 2000-kg truck traveling north at 25 m/s (55.9
mph). The cars lock together in such a way as to prevent them from
separating or rotating significantly. One second before the
collision, the car is located at position (x,y) = (-20,0) m and the
truck is located at position (x,y) = (0,-25) m.
Part a) Calculate the x-coordinate of the center of mass of the...
