Question

Consider the following two blocks A and B with the mass of
*m*_{a}= 7 kg and *m*_{b} = 4 kg.
They are moving in the same direction along the x-axis on a
horizontal frictionless surface with initial velocities
*v*_{ai}= 30 m/s and *v*_{bi}= 20
m/s. The two blocks collide head-on and there is no change in the
line of motion of either object. If the collision is elastic, find
the final velocity of block A.

Answer #1

Blocks A (mass 5.50 kg ) and B (mass 13.00 kg
) move on a frictionless, horizontal surface. Initially, block
B is at rest and block A is moving toward it at
3.00 m/s . The blocks are equipped with ideal spring bumpers. The
collision is head-on, so all motion before and after the collision
is along a straight line. Let +x be the direction of the
initial motion of A.
Part A: Find the maximum energy stored in the...

Blocks A (mass 5.00 kg) and B (mass 7.00 kg) move on a
frictionless, horizontal surface. Initially, block B is at rest and
block A is moving toward it at 4.00 m/s. The blocks are equipped
with ideal spring bumpers. The collision is head-on, so all motion
before and after the collision is along a straight line. Let +x be
the direction of the initial motion of block A. Find the maximum
energy stored in the spring bumpers. Find the...

Blocks A (mass 3.5 kg) and B (mass 5.5 kg) move on a
frictionless, horizontal surface. Initially, block B is at rest and
block A is moving toward it at 2.0 m/s. The blocks are equipped
with ideal spring bumpers (as in Example 8.10, Section 8.4). The
collision is head-on, so all motion before and after the collision
is along a straight line.
(a) Find the maximum energy stored in the spring bumpers, in
Joules.
(b) Find the velocity of...

Block A of mass (mA) = 9.0 kg with an initial speed
(uA) = 2.1 m/s collides with a Block B of mass
(mB) = 27 kg which had an in initial speed
(uB) = 0.50 m/s, as shown int the figure. The surface is
frictionless, and the blocks suddenly collide and couple. After the
collision, Find the common speed (Vf) that the blocks
travel with.
a) 0.5 m/s
b) 0.9 m/s
c) 0.1 m/s
d) 0.6 m/s

Two blocks move along a linear path on a nearly frictionless air
track. One block, of mass 0.112 kg, initially moves to the right at
a speed of 5.40 m/s, while the second block, of mass 0.224 kg, is
initially to the left of the first block and moving to the right at
7.40 m/s. Find the final velocities of the blocks, assuming the
collision is elastic.
velocity of the 0.224 kg block

velocity of the 0.112 kg block...

Consider a collision between two carts, one of mass mA= 5 kg and
the otherof mass mB= 7 kg, on a frictionless track. (A). Find the
final velocity of Cart A, if both objects are initially moving in
opposite directions toward each other at 12 m/s, and Cart B
completely stops due to the collision. (B). Is this an elastic or
inelastic collision? Why?

Mass A (3 kg) and Mass B (1 kg) collide head‐on on a
frictionless surface. A was initially moving to
the
right at 0.2 m/s, while B was moving at 0.4 m/s to the
left. The collision is completely elastic.
a) Find the velocity (magnitude and direction) for each mass after
the collision. Treat this as a one
dimensional problem.
b) Find the change in momentum for each
mass. Compare.
c) Find the change in kinetic energy for each
mass. Compare.

Two blocks of masses m1 = 1.95 kg and m2 = 3.90 kg are each
released from rest at a height of h = 6.00 m on a frictionless
track, as shown in the figure below, and undergo an elastic head-on
collision. (Let the positive direction point to the right. Indicate
the direction with the sign of your answer.) Two blocks are on a
curved ramp similar in shape to a half-pipe. There is a flat
horizontal surface with opposite...

A
6.0-kg block moving at 9.0 m/s to the right collides head-on with
another 12.0-kg block moving at 3.0 m/s to the left. What are the
velocities of the two blocks after the collision if the collision
is elastic?

A ball with a mass of 1.1 kg is initially at rest. It is struck
by a second ball having a mass of 1.3 kg, initially moving with a
velocity of 3.5 m/s toward the right along the x axis. After the
collision, the 1.3 kg ball has a velocity of 2.7 m/s at an angle of
35? above the x axis in the first quadrant. Both balls move on a
frictionless, horizontal surface. Do not assume that the collision...
