Question

An automobile has a mass of 2300 kg and a velocity of positive 16 m/s. It makes a rear end collision with a stationary car whose mass is 1800 kg. The cars locked bumpers and skid off together with the wheels locked. A) what is the velocity of the two cars just after the collision. B) find the impulse, magnitude and direction, the acts on the skidding cars from just after the collision until they come to a halt. C) if the coefficient of kinetic friction between the wheels of the cars and the pavement is 0.80, determine how far the cars skid before coming to rest

Answer #1

A 930 kg sports car collides into the rear end of a 2300 kg SUV
stopped at a red light. The bumpers lock, the brakes are locked,
and the two cars skid forward 3.1 m before stopping. The police
officer, knowing that the coefficient of kinetic friction between
tires and road is 0.80, calculates the speed of the sports car at
impact.
What was that speed?

A 920 kg sports car collides into the rear end of a 2300 kg SUV
stopped at a red light. The bumpers lock, the brakes are locked,
and the two cars skid forward 2.8 m before stopping. The police
officer, knowing that the coefficient of kinetic friction between
tires and road is 0.31, calculates the speed of the sports car at
impact. What was that speed?

Two identical cars each of mass 1.8 metric tons, collide head-on
during a crash-test. One car was moving at speed 50 mi/hr before
the collision, the other car was moving at 63 mi/hr. After the
collision, the two cars skid together until they come to rest. What
was the total impulse magnitude exerted by friction on the cars
after the collision? Consider the same situation as before, only
after the crash, the cars skid for a short distance before ending...

Two identical cars each of mass 1.8 metric tons, collide head-on
during a crash-test. One car was moving at speed 52 mi/hr before
the collision, the other car was moving at 66 mi/hr. After the
collision, the two cars skid together until they come to rest. What
was the total impulse magnitude exerted by friction on the cars
after the collision?

You have been hired as an expert witness in a court case
involving an automobile accident. The accident involved a car of
mass 1910 kg (car A) which approached a stationary car of mass 1000
kg (car B). The driver of car A applied his brakes 13 m before he
crashed into car B. After the collision, car A slid 17 m while car
B slid 30 m. The coefficient of kinetic friction between the locked
wheels and the road...

A block of mass m1 = 1.20 kg moving at v1 = 1.20 m/s undergoes a
completely inelastic collision with a stationary block of mass m2 =
0.500 kg . The blocks then move, stuck together, at speed v2. After
a short time, the two-block system collides inelastically with a
third block, of mass m3 = 2.60 kg , which is initially at rest. The
three blocks then move, stuck together, with speed v3. Assume that
the blocks slide without...

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...

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.

A ball with a mass of 1.50 kg travelling +2.00 m/s collides with
a stationary ball with a mass of 1.00 kg. After the collision, the
velocity of the 1.50 kg ball is +0.40 m/s. What is the velocity of
the 1.00 kg ball after the collision?
Select one:
a. - 0.7 m/s
b. + 3.6 m/s
c. + 2.4 m/s
d. + 1.8 m/s
An 18 000 kg freight car travelling 1.75 m/s[E] collides with a
27 000 kg...
