Question

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?

Answer #1

Thanks!please rate it up

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 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?

A car with a mass 1500kg traveling East 10m/s collides with a
truck with a mass 2000kg traveling West at 12m/s. After the
collision, the two are stuck together.
A) Find the final speed.
B) How much kinetic energy was lost?

Car A of mass 1,274 kg is traveling east at 13.2 m/s when it
collides with car B of mass 1,596 kg which is traveling at 14.6 m/s
at 71.4 degrees N of W. The two cars stick together after the
collision. What is the magnitude of the final velocity of the
cars?

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 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 4000kg truck traveling with a velocity of 20m/s due
on South collides head on with a 1320kg car traveling with a
velocity of 10m/s due north. two vehicles stick together after the
collision.
A. what are the magnitude and direction of the
momentum of each vehicle prior to the collision?
B. what are the magnitude and direction of the
velocity of both vehicles after they collide?

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

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?

A car of mass m1 = 2000.0 kg is moving at speed v1i = 20.0m/s
towards East. A truck
of mass m2 = 5000.0 kg is moving at speed v2i = 10.0m/s towards
North. They collide at an
intersection and get entangled (complete inelastic
collision).
1. What is the magnitude and direction of the final velocity of the
entangled automobiles?
2. How much kinetic energy is lost in the collision. That is,
calculate the change in the
kinetic energy of...
