Question

A small, 200 gg cart is moving at 1.90 m/sm/s on a frictionless track when it collides with a larger, 5.00 kgkg cart at rest. After the collision, the small cart recoils at 0.810 m/sm/s .

What is the speed of the large cart after the collision?

Express your answer with the appropriate units.

A 2.2 kgkg block slides along a frictionless surface at 1.4 m/sm/s . A second block, sliding at a faster 4.4 m/sm/s , collides with the first from behind and sticks to it. The final velocity of the combined blocks is 2.4 m/sm/s .

What was the mass of the second block?

Express your answer with the appropriate units.

Answer #1

A small, 250 gg cart is moving at 1.80 m/sm/s on a frictionless
track when it collides with a larger, 3.00 kgkg cart at rest. After
the collision, the small cart recoils at 0.820 m/sm/s .
v = _____

A small, 300 gg cart is moving at 1.40 m/sm/s on a frictionless
track when it collides with a larger, 4.00 kg cart at rest. After
the collision, the small cart recoils at 0.810 m/s.
What is the speed of the large cart after the collision?

A small, 100 g cart is moving at 1.90 m/s on an air track when
it collides with a larger, 2.00 kg cart at rest. After the
collision, the small cart recoils at 0.820 m/s . What is the speed
of the large cart after the collision?

A 120 gg ball moving to the right at 4.2 m/sm/s catches up and
collides with a 450 gg ball that is moving to the right at 1.2
m/sm/s
Part A: If the collision is perfectly elastic, what is the speed
of the 120 gg ball after the collision?
Express your answer to two significant figures and
include the appropriate units.
Part B : If the collision is perfectly elastic, what is the
direction of motion of the 120 gg...

A)A 2.9 kg block of wood sits on a table. A 0.0035 kg bullet,
fired horizontally at a speed of 440 m/s, goes completely through
the block, emerging at a speed of 140 m/s.What is the speed of the
block immediately after the bullet exits?
Answer in m/s
B)A small, 0.43 kg cart is moving at 1.4 m/s on an air track
when it collides with a larger, 5 kg cart at rest. After the
collision, the small cart recoils...

1. On a frictionless horizontal air table, puck A (with mass
0.252 kgkg ) is moving toward puck B (with mass 0.375 kgkg ), which
is initially at rest. After the collision, puck A has velocity
0.122 m/sm/s to the left, and puck B has velocity 0.651 m/sm/s to
the right.
Calculate ΔKΔKDeltaK, the change in the total kinetic energy of
the system that occurs during the collision.
2. A 2.5 kgkg block of wood sits on a frictionless table....

A 144-gg baseball moving 29 m/sm/s strikes a stationary
5.25-kgkg brick resting on small rollers so it moves without
significant friction. After hitting the brick, the baseball bounces
straight back, and the brick moves forward at 1.24 m/sm/s .

A 50.0 gg marble moving at 2.00 m/sm/s strikes a 26.0 gg marble
at rest. Note that the collision is elastic and that it is a
"head-on" collision so all motion is along a line.
What is the speed of 50.0 gg marble immediately after the
collision?
What is the speed of 26.0 gg marble immediately after the
collision?

A cart with mass 271 g, moving on a frictionless linear air
track at an initial speed of 1.08 m/s hits an initially stationary
cart of unknown mass. After the collision, the first cart continues
in its original direction at 0.92 m/s. The collision is
elastic.
(a) What is the mass of the second cart?
(b) What is the speed of the second cart?
A block of mass 0.29 kg is placed on top of a light, vertical
spring of...

An air-track cart with mass m1=0.34kg and initial speed
v0=0.80m/s collides with and sticks to a second cart that is at
rest initially.
Part A If the mass of the second cart is m2=0.54kg, how much
kinetic energy is lost as a result of the collision? Express your
answer to two significant figures and include appropriate
units.
