Question

A 2.50 kg mass moving 7.50 m/s to the right collides head on with a 4.90 kg mass. After the collision the 2.50 kg mass is moving 5.00 m/s to the left and the 4.90 kg mass is moving 4.88 m/s to the right.

a. Calculate the velocity of the 4.90 kg mass before the collision

b. If the collision lasts for 0.0625 seconds calculate the force that acted on each mass during the collision.

Answer #1

A
cart of mass 2.50 kg moving with a speed of 4.00 m/s collides
head-on with a 1.50 kg cart at rest. If the collision is elastic,
what will be the speed and direction of each cart after the
collision?

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 7.50 kg bowling ball moving at 4.00 m/s makes an elastic head
on collision with a 2.50 kg bowling pin initially at rest. Find the
velocity of the bowling pin after the 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) 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...

A ball of mass 0.250 kg that is moving with a speed of 5.5 m/s
collides head-on and elastically with another ball initially at
rest. Immediately after the collision, the incoming ball bounces
backward with a speed of 3.1 m/s . Calculate the velocity of the
target ball after the collision. Calculate the mass of the target
ball.

A ball of mass 0.310 kg that is moving with a speed of 5.7 m/s
collides head-on and elastically with another ball initially at
rest. Immediately after the collision, the incoming ball bounces
backward with a speed of 3.1 m/s .
1. Calculate the velocity of the target ball after the
collision.
2. Calculate the mass of the target ball.

A ball of mass 0.265 kg that is moving with a speed of 5.1 m/s
collides head-on and elastically with another ball initially at
rest. Immediately after the collision, the incoming ball bounces
backward with a speed of 3.5 m/s .
Part A: Calculate the velocity of the target ball after the
collision.
Part B: Calculate the mass of the target ball.

A 5.0-kg mass moving at 8.0 m/s collides head-on with a 3.0-kg
mass initially at rest If the collision is perfectly elastic, what
is the speed of the masses just after the collision? Is the kinetic
energy conserved?

An object of mass 2.90 kg, moving with an initial velocity of
4.90 î m/s, collides with and sticks to an object of mass 1.91 kg
with an initial velocity of -3.97 ĵ m/s. Find the final velocity of
the composite object. v with arrow = (____ î + ____ ĵ) m/s
