Question

1. An 1850-kg truck traveling westward at 70.5 km/h collides at an intersection with a 975-kg automobile traveling northward at 97.8 km/h. (Hint: Convert km/h to m/s.) The vehicles lock together after the collision. (a) Sketch the situation and label the variables. (b)What is the x- and y-component of the initial momentum? (c) What is the momentum (vector) before collision? (d) Where’s the truck and the automobile combined headed to immediately after collision? (e) What is the momentum after collision? Explain your answer

Answer #1

A truck with a mass of 1800 kg traveling 32 miles per hour
collides with a car (mass = 1100 kg) sitting at a stop sign. The
two lock together and both cars slide into the intersection. Both
drivers slam on the brakes in desperation. The coefficient of
friction between the tires and the road is 0.58.
a. What is the momentum of each car before the collision?
b. What is their combined momentum after the collision? Justify
your answer....

A 1200-kg sportscar is heading east at 75 km/h toward the east
when it collides with a 3350-kg truck traveling south at 50 km/h
and they stick together upon collison. Both vehicles were
driverless cars, so nobody was injured in this collision. What is
the direction of motion of the wreckage after collision?

A car with a mass of 2200kg, travelling at 60.0 km/h [E],
collides with a car of mass 1300 kg that is travelling at 30.0 kg/h
[E], and the two cars lock bumpers.
a) Calculate the velocity of the vehicles immediately after the
perfectly inelastic collision.
b) Calculate the total momentum of the two cars before and after
the collision.
c) Determine the decrease in kinetic energy during the
collision.

A truck of mass 25947 kg is moving east at 63 km / h collides a
car of mass 1271 kg moving west at 92 km / h. The Collision is
completely inelastic and takes place on a frictionless road.
Determine the fractional loss of kinetic energy after the
Collision. Give an answer to one decimal place. Remember to add
unit% after the numerical value.

1. A 1000.0 kg car is moving at 20 km/h. If a 2000.0 kg truck
has 25 times the kinetic energy of the car, how fast is the truck
moving? 2. A car of mass 1005 kg collides head-on with a parked
truck of mass 2010 kg. Spring mounted bumpers ensure that the
collision is essentially elastic. If the velocity of the truck is
15 km/h (in the same direction as the car's initial velocity) after
the collision, what was...

A 1990 kg truck traveling north at 45 km/h turns east and
accelerates to 56 km/h. (a) What is the change in the truck's
kinetic energy? (b) What is the magnitude of the change in its
momentum?

A 2500 kg truck is traveling west through an intersection at 3.0
m/s when it is hit simultaneously from the side and the rear. One
car is a 1500 kg compact traveling south at 4.0 m/s. The other is a
1700 kg midsize traveling west at 8.0 m/s. The three vehicles
become entangled and slide as one body after collision. What is
their velocity (magnitude and direction) immediately after the
collision?

25.) Suppose you are traveling in a bus at highway speed on a
nice summer day and the momentum of an unlucky bug is suddenly
changed as it splatters onto the front window. a) Compared to the
force that acts on the bug, how much force acts on the bus. (more)
(the same) (less)
b) Although the momentum of the bus is very large compared to
the momentum of the bug, the change in momentum of the bus compared
to...

A truck of mass 5000 kg was moving north at 45 km/h when it
collided with a car of mass 1250 kg moving east at 90 km/h. Find
the magnitude and direction of thre velocity of the vehicles after
the collision, assuming they became entangled and moved
together.

1.You are headed down a highway at 30.0m/s in your 1210 kg car
texting away on your phone when you just happen to look up and see
that you have crossed the centerline and are colliding with a 36300
kg truck going 30.0m/s in the opposite direction. Momentum is
conserved in all collisions. Sketch and label a diagram choosing
which direction is positive.
A.what is the total momentum of the two-vehicle system keeping
in mind that the momentum is a...
