Question

A object of mass .849kg slids along a frictonless surface. Initally, the object moves with 11m/2 in a direction 15 below the positive x axis. A second object of mass .279kg is now shot from below at v in the positive y direction. It hits the first object and sticks to it. After the impact, the collision it moves in direction 63 above the positive x axis.

1) determine the speed the of 2nd object before impact

2) Determine the final speed collided objects after they stick together

Answer #1

Two objects collide on a frictionless surface. Object A with a
mass of 200g is moving in the positive x−direction with a speed of
1.0ms while object B, with a mass of 250g, is at rest. After the
collision object B is seen to have a speed of 0.40ms at an angle of
36.87◦ with respect to the positive x−axis. Find the magnitude and
direction of the object A after the collision. Find the kinetic
energy of the system before...

One object moves in the positive x direction with speed v.
Another object moves in the opposite direction with the same speed
but with one half the mass of the first object. The two objects
have a completely inelastic collision. What is the final x
component of the velocity?

A particle of 1kg moving with 11m/s in the positive x-axis
direction makes a head-on elastic collision with a stationary
particle of mass 3kg. After collision, the two particles rebound
along the x-axis. What is the final velocity of the lighter
object?

Two particles, ?1 and ?2, undergo a glancing elastic collision.
Initially mass ?1 moves along the negative ?-direction and ?2 along
the positive ?-direction, both with speed ?? . After the collision
?1 moves along the negative ?-direction. Given that ?2 = 8 ?1, find
the magnitudes of the velocities of both particles in terms of ?? ,
and the direction of mass ?2.

First, an object 1 with mass m and an object 2 with mass 2 m are
moving on a straight line at velocities v1i=1.00 m/s and v2i= -2.00
m/s. Two objects collided inelastically, and the velocities of
object 1 and object 2 changed to v1f and vf2, respectively. The
velocity is positive in the right direction, and no external force
is acting on these two objects. Find v1f and vf2 for cases (1) and
(2) below, respectively.
(1) When two...

Object 1, with mass m1 and speed 5.3 m/s, slides along
on a frictionless ice rink and then undergoes
a one-dimensional elastic collision with a standstill object 2,
with mass m2 = 0.44m1. The two objects
then slide into a region where the coefficient of kinetic friction
is 0.56; there they stop. How far into that
region do (a) object 1 and (b) object 2 slide? (c) Assume the
collision is inelastic, and that the objects
stick together. How far...

A puck with a mass of 1.2 kg moves with a velocity of 5 m/s in
the x-direction. It collides with a 1.6 kg puck which is initally
stationary. After the collision, the second puck moves at a
velocity of 1.44 m/s at an angle of 33 degrees below the x
axis.
A) What is the angle of the first puck after the collision?
B)What is the velocity of the first puck after the
collision?

An air hokey puck (A), of mass m, is moving along the x-axis
with speed vo. It hits an identical stationary puck (B).
After the collision, puck A is moving 30 degrees above the x-axis
and puck B moves 45 degrees below the x-axis.
a) Find the final speed of puck A in terms of m, vo,
and the angles defined.
b) Find the change in kinetic energy of the system.

1) Consider an object of mass m1 =
0.425 kg moving with a uniform speed of 6.65 m/s on a frictionless
surface. This object makes an elastic head-on collision with
another object of mass m2 = 0.555
kg which is initially at rest. (a) Find the speed of
m1 immediately after collision. (b)
Find the speed of m2 immediately after
collision.
2) An object of mass m1 = 0.395
kg starts from rest at point and slides down
an incline surface that makes...

An object with a mass of 47.3 g is moving uniformly with a
velocity of 39.9 m/s along the positive x-axis. A second object, of
mass 36.0 g, is moving at +8.9 m/s along the same line, in front of
the first mass.
a) Using the usual sign conventions, what is the velocity of the
centre-of-mass of the two objects?
b) What is the velocity of the first particle, in the zero
momentum frame, after an elastic collision?
c) Using...
