Question

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?

Answer #1

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 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 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 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 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...

A 1450-kg car moving east at 17.0 m/s collides with a 1850-kg
car moving south at 15.0 m/s, and the two cars connect
together.
What is the direction of the cars right after the collision?
Enter the angle in degrees where positive indicates north of east
and negative indicates south of east.

Mass #1 of 5.0 kg is moving at 2.0 m/s in the + x-direction, and
collides with mass #2 of 10. kg that is initially at rest, on a
frictionless horizontal surface. They collide elastically. Find
each velocity, after the collision.

A 4.34-kg toy car with a speed of 4.13 m/s collides with a
stationary 1.00-kg car. After the collision, the cars are locked
together with a speed of 3.6 m/s. How much kinetic energy is lost
in this collision?

A) A block of mass m1=6.0 kg is initially moving at 5.0 m/s to
the right and collides inelastically with an initially stationary
block of mass m2=18.0 kg. The two objects become stuck together.
Find the final velocity of the two blocks.
B) A block of mass m1=6.0 kg is initially moving at 5.0 m/s to
the right and collides elastically with an initially stationary
block of mass m2=18.0 kg.
After the collision, block m2 is moving to the right...

A 1450-kg car moving east at 17.0 m/s collides with a 1880-kg
car moving south at 15.0 m/s, and the two cars connect
together.
How much kinetic energy was converted to another form during the
collision? kJ
