Question

a
2kg ball moving at 3 m/s strikes a 1 kg ball at rest in a one
dimensional elastic collision.

find the speed of the first ball after the collision. find the
speed of the second ball after the collision

Answer #1

A 1-kg ball moving at 5 m/s strikes a 2-kg ball moving at 4 m/s
in the opposite direction. After the collision the 2-kg ball
continues moving in the same direction at 1.1 m/s. (a) Find the
velocity of the 1-kg ball after the collision. (b) Find the change
in the kinetic energy.

A billiard ball moving at 5.80 m/s strikes a stationary ball of
the same mass. After the collision, the first ball moves at 4.97
m/s, at an angle of 31.0° with respect to the original line of
motion.
(a) Find the velocity (magnitude and direction) of the second
ball after collision.
______ m/s
° (with respect to the original line of motion, include the sign of
your answer; consider the sign of the first ball's angle)(b) Was
the collision inelastic...

Billiard ball A of mass mA = 0.125 kg moving with speed vA =
2.80 m/s strikes ball B, initially at rest, of mass mB = 0.138 kg .
As a result of the collision, ball A is deflected off at an angle
of θ′A = 30.0∘ with a speed v′A = 2.10 m/s, and ball B moves with a
speed v′B at an angle of θ′B to original direction of motion of
ball A.
(a) Solve these equations for...

A 41 g marble moving at 2.0 m/s strikes a 21 g marble at rest.
Assume the collision is perfectly elastic and the marbles collide
head-on. a:What is the speed of the first marble immediately after
the collision? b:What is the speed of the second marble immediately
after the collision?

A 50 g marble moving at 2.2 m/s strikes a 23 g marble at rest.
Assume the collision is perfectly elastic and the marbles collide
head-on.What is the speed of the first marble immediately after the
collision?What is the speed of the second marble immediately after
the collision?

Billiard ball A of mass mA = 0.130 kg moving with speed vA =
2.65 m/s strikes ball B, initially at rest, of mass mB = 0.140 kg .
As a result of the collision, ball A is deflected off at an angle
of 30.5 ∘ with a speed vA1 = 2.35 m/s .
C.) Solve for the speed, vB1, of ball B. Do not assume the
collision is elastic.
D.) Solve for the angle, θB, of ball B. Do...

A ball of mass 0.440 kg moving east (+x direction) with a speed
of 3.60 m/s collides head-on with a 0.260 kg ball at rest. If the
collision is perfectly elastic, what will be the speed and
direction of each ball after the collision?

A ball of mass 0.484 kg moving east (+xdirection) with
a speed of 3.76 m/s collides head-on with a 0.242 kg ball at rest.
Assume that the collision is perfectly elastic.
A)What is be the speed of the 0.484-kg ball after
the collision? B)What is be the direction of the velocity of the
0.484-kg ball after the collision? C)What is the speed of the
0.242-kg ball after the collision? D)What is the direction of the
velocity of 0.242-kg ball after...

A ball of mass 0.458 kg moving east (+x direction) with a speed
of 3.76 m/s collides head-on with a 0.229 kg ball at rest. Assume
that the collision is perfectly elastic.
