c) Where does that energy go?

Answer #1

Question 1: A ball of clay (m= 20 g) is thrown horizontally at a
block of wood (m=1.0 kg) that is sitting at rest on a frictionless
surface. The ball of clay has a speed of 30 m/s. When it hits the
block, it sticks to it. a) (1 point) What type of collision is
this? b) (3 points) What is the speed of the block and the clay
right after the collision? c) (2 points) Calculate the impulse
(change...

two
balls of clay suffer a headon (1 - D) ) collision and stick
together Ball has a mass of 200 g and initially moving with a
velocity of 45 cm / s to the right has mass of 600 g and is
initially moving at 25 cm / s to the leftWhat their final velocity
in cm/s?

A ball with mass of 0.025 kg is thrown horizontally with
velocity of 1.5 m/s toward a wall in positive X direction. It
collides with the wall, then bounces back to the left with velocity
of 1.0 m. The Collison takes 0.015s.
What is the total initial momentum?
b) What is the total final momentum?
c)What is change in momentum?
d)What is the impulse?
e) What is the average force acting on the wall by the ball
during the collision?...

A steel ball of mass 200g moving with a velocity of 10 m/s
collides elastically with another ball of same mass at rest, then
calculate the followings. (your answer must be in SI units) (4
points)
a. Total momentum of the system before collision =
b. Total Kinetic energy of the system before collision =
c. Total momentum of the system after collision =
d. Total Kinetic energy of the system after collision

a
1.2 kg ball moving with a velocity of 8.0m/s collides head on with
a stationary ball and bounces back at a velocity or 4.0 m/s. If the
collision is perfectly elastic, calculate (a) the mass of the other
ball (b) the velocity of the other ball after the collision (c) the
momentum of each ball before and after the collision (d) the
kinetic energy of each ball before and after the collision

A car of mass m1 = 2000.0 kg is moving at speed v1i = 20.0m/s
towards East. A truck
of mass m2 = 5000.0 kg is moving at speed v2i = 10.0m/s towards
North. They collide at an
intersection and get entangled (complete inelastic
collision).
1. What is the magnitude and direction of the final velocity of the
entangled automobiles?
2. How much kinetic energy is lost in the collision. That is,
calculate the change in the
kinetic energy of...

ball weighing 1 pound is thrown vertically upward from a point 6
ft above the surface of the earth with an initial velocity of 18
ft/sec. As it rises it is acted upon by air resistance that is
numerically equal to (1/16)*v (in pounds) where v is the velocity
(in feet per second).
How high will the ball rise?
NOTE: Before you attempt to answer, please take into consideration
that this problem is for a Differential Equations class (NOT A...

Baseball: a baseball b, weighing .14 kg is thrown at 44 m/s at
the batter. The batter swings the bat B, which weighs 0.95 kg at 39
m/s hitting the baseball. Assume precise conservation of energy and
momentum and the motion during the hit is exactly horizontal.
Calculate the conservation of energy and momentum and solve for the
final velocities of the ball and bat. What is the total mechanical
kinetic energy? If the impulse is rectangular (goes to maximum...

A 6.85 kg bowling ball moving at 10.0 m/s collides with a 1.60
kg bowling pin, scattering it with a speed of 8.00 m/s and at an
angle of 32.0° with respect to the initial direction of the bowling
ball. (
a) Calculate the final velocity (magnitude in m/s and direction
in degrees counterclockwise from the original direction) of the
bowling ball.
______magnitude m/s
__________direction ° counterclockwise from the original
direction of the bowling ball
(b) Ignoring rotation, what was...

1. A rubber ball with a mass of 1.35 kg is stuck in a tree. To
knock it out, you throw a golf ball with a mass of 0.0450 kg at it.
The golf ball hits the rubber ball with a speed of 20.0 m/s and
bounces off with a speed of 10.0 m/s. The golf ball is moving in
the same direction horizontally after the collision as it was
before it hit the rubber ball. When the golf ball...
