Question

A 1000-kg sports car is moving north at speed 15 m/s on a level road when it collides with a 2000-kg truck driving east on the same road at speed 10 m/s. The two vehicles remain locked moving together after the collision at the origin of x-y plane. Assume that the rolling friction is too small to be ignored.

A) explain what type of collision it is

B) indicate the vector momentum by showing its magnitude and the (direction) angle after collision

C) calculate the magnitude and the direction (theta) of the momentum and velocity of two wreckage cehicles just after impact

Answer #1

q

A 1000-kg car moving north with a speed of 25.0 m/s collides
with a 2000- kg truck moving at an angle of 30° north of west with
a speed of 20.0 mjs. After the collision, the car and the truck
stuck together. What is the magnitude of their common velocity
after the collision?

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 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...

A 2,500-kg car moving east at 10.0 m/s collides with a 3,000-kg
car moving north. The cars stick together and move as a unit after
the collision, at an angle of 35.0 degrees north of east and at a
speed of 5.55 m/s. Find the speed of the 3,000-kg car before the
collision.
__________ m/s north

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 1500 kg car moving east with a velocity V collides at an
intersection with a 3000.0 kg truck moving south with a speed of
13.5m/s. After the vehicles stick together and the wreckage makes
an angle of 50 degrees north of east. The truck driver claims that
the car was speeding, the speed limit is 30miles/hr. Was the car
speeding? explain with facts

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 2500 kg car moving east at 10.0 m/s collides with a 3000 kg
car moving north. The cars stick together and move as a unit after
the collision, at an angle of 47.0° north of east and at a speed of
6.66 m/s. Find the velocity of the 3000 kg car before the
collision. m/s north

A 5.0 kg toy-car moving with a speed of 10.0 m/s in +x direction
collides with a 7.0 kg toy truck moving with a velocity of 15.0 m/s
in a direction 37 degrees above +x direction. What is the velocity,
both the magnitude and direction, of the two objects after the
collision, if they remain stuck together?

A truck with mass 3000 kg is driving at 20 m/s north. It
collides with a car of mass 1200 kg traveling east towards the
truck at 30 m/s. How fast, and in what direction, will the two be
traveling after the collision if it is perfectly inelastic?
a.
16.7 m/s at 31 degrees north of east.
b.
16.7 m/s at 59 degrees north of east.
c.
36.1 m/s at 33.7 degrees north of east.
d.
50 m/s Northeast.
