Consider two objects which collide. The first object has a mass of 1 kg which is moving with an initial velocity of 4 m/s to the right. It hits a second object of 4 kg which is initially moving with an initial velocity of 4 m/s to the left. After the collision, the second object is moving 2 m/s to the left.

What is the final velocity of the first object? Show your work.

a)2.82 m/s to the left

b)2.82 m/s to the right

c)4 m/s to the left

d)4 m/s to the right

e)8 m/s to the left

f)8 m/s to the right

g)20 m/s to the left

h)20 m/s to the right

i)None of these

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 30 m/s. The masses of the two objects are 3.0 and 7.6 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is...

Two asteroids collide at a 90o angle.  Before the collision, one asteroid, with a mass of 15,000 kg, is moving with a velocity of 25 m/s to the right.  The other asteroid, with a mass of 25,000 kg, is moving with a velocity of 35 m/s in a downward direction.  They collide so that the first asteroid (the smaller one) hits the left side of the second asteroid, and then continues to move forward, but with only 1/5 of its original speed.  Find the...

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.

Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Object A has a mass of mA = 16.0 kg and an initial velocity of v0A = 7.95 m/s, due east. Object B, however, has a mass of mB = 30.5 kg and an initial velocity of v0B = 4.85 m/s, due north. Find the magnitude of the final velocity of the two-object system...

Two rubber objects undergo a collision that we will approximate as being elastic. The first object has mass 12.0 kg, and the second object has mass 12.0 kg. Before the collision, the first object is traveling at 4.00 m/s and the second object is traveling at -4.00 m/s (negative meaning in the opposite direction). What is the velocity of the second object, after the collision?

Consider the following two blocks A and B with the mass of ma= 7 kg and mb = 4 kg. They are moving in the same direction along the x-axis on a horizontal frictionless surface with initial velocities vai= 30 m/s and vbi= 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.
