Question

Two balls traveling in opposite directions collide head on.
**Ball _{1}** is traveling in the positive x
direction at a speed of

**a)** If we assume that the two balls are made of
clay and become one mass during the collision what is their
combined final velocity? **(Think conservation of momentum
and be careful of your signs)**

**b)** If we assume that they are made of steel and
do not become one mass and the collision can be treated as
an**elastic collision** what is the final velocity of
**Ball _{1}**. (Be careful of your signs here
too)

**c)** Consider Ball_{1}’s change in
momentum during the collision and **calculate the
impulse** that it feels as a result of the impact.

**d)** If the contact takes place over **Δt =
0.03 seconds** what is the force exerted on
**Ball**

Answer #1

We have two balls of equal mass on a frictionless table. Ball 1
is moving at a speed v0, while Ball 2 is at rest. The two balls
collide elastically in a straight line. The final velocities of the
two balls are...
A. V1 = 0 and V2= v0
B. V1= 1/2V0 and V2= 1/2V0
C. V1= -V0 and V2= 2V0
D. V1= -1/2V0 and V2= 3/2V0

Two identical pucks collide on an air hockey table. One puck was
originally at rest. If the incoming puck has a velocity of 6.50 m/s
along the +x-axis and scatters to an angle of 32.0° above the
+x-axis.
A) What is the velocity (magnitude and direction) of the second
puck? (You may use the result that θ1 − θ2 = 90° for elastic
collisions of objects that have identical masses.)
Velocity (magnitude) = _______ Velocity (direction) = ________
below +x-axis...

Two cars approach an ice-covered intersection. One car, of mass
1.21 X 10^3 kg, is initially traveling north at 12.1 m/s. The other
car, of mass 1.62 X 10^3 kg, is initially traveling east at 12.1
m/s. The cars reach the intersection at the same instant, collide,
and move off coupled together. Find the velocity of the center of
mass of the two-car system just after the collision.
magnitude: ______
direction: _____ north of east

A halfback with a mass m1 = 95 kg is running up field with a
speed of v1 = 7.6 m/s. He is tackled by an opponent with a mass m2
= 125 kg, who approaches the halfback at an angle β = 30°with a
velocity v2 = 4.2 m/s. Assume the collision is perfectly
inelastic.
a) Calculate the magnitude and direction of the resultant
velocity of the two players just after the tackle. (3 pts.)
b) Calculate the change...

10. A car with mass 1000 kg travels at 30 m/s, while a second
car with mass 1500 kg travels at 20 m/s. The two cars collide in a
perfectly inelastic collision. What is the final velocity (speed
and direction) if the first car was travelling north and the second
travelling south? If the first car were travelling north and the
second were travelling east?

One yak, (m1) with a mass 500 kg is sitting still on a
frictionless surface when a smaller yak (m2) charges into it at a
velocity of 15 m/s in a direction 30° north of west. After the two
collide the smaller yak is traveling due west while the larger yak
is traveling due north. The smaller yak’s final speed is twice that
of the larger yak. What is (a) the mass and (b) the final speed of
the smaller...

When a cue ball strikes the 8-ball, we can assume that the
collision is elastic. An 8-ball has a mass of 0.160 kg, and we have
made a special cue ball, with a lead core, to have a mass that is 3
times as much as the 8-ball's mass, or 0.480 kg. Let's say this
heavy cue ball, initally moving at 1.5 m/s, strikes the 8-ball, and
the 8-ball's subsequent velocity is in the same direction as the
initial velocity...

1. Usain Bolt sprints along the track, with his feet pushing
down and behind him. Therefore the track actually pushes Usain Bolt
along the track. Group of answer choices True or False
2.You study two objects in motion, Object J and Object S. Each
object has its own velocity graph, with same time and velocity
scales. The slope of each graph is positive, upward and to the
right ⁄ but Object J's tilt angle is only 10º and Object
S's tilt...
