After a completely inelastic collision, two objects of the same mass and same initial speed are found to move away together at 1/5 their initial speed. Find the angle between the initial velocities of the objects.
PLEASE WORK OUT. THANKS.

let initial angle be θ1 and θ2
conservation og momentum along
mvcosθ1 + mvcosθ2 = 2mv/5
vcosθ1 + vcosθ2 = 2v/5
cosθ1 +cosθ2 = 2/5 --eqtn 1
vsinθ1 = vsinθ2
so θ1 = θ2
2cosθ1 = 2/5
cosθ1 =1/5
θ1 = 78.46 degree
so angle between their velocity = 2 * θ1 = 156.9 degree

Q3. In a two dimensional 4 points completely inelastic collision two objects of the same mass and same initial speed collides. After that they move away together at half their initial speed. The angle between the initial velocities (theta+phi) of the objects is * o 20 degrees O 30 degrees O 60 degrees O 72 degrees O 90 degrees O 120 degrees
After a completely inelastic collision between two objects of equal mass, each having initial speed, v, the two move off together with speed v/4. What was the angle between their initial directions?
A block of massm1 = 1.30kg moving at v1 = 2.00m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.100kg . The blocks then move, stuck together,at speed . After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.60kg , which is initially at rest. The three blocksthen move, stuck together, with speed v3 .

. Two objects of the same mass move along the same line in opposite directions. The first mass is moving with speed v. The objects collide, stick together, and move with speed 0.100v in the direction of the velocity of the first mass before the collision. 1.How much kinetic energy is lost during the collision?
Two equal mass objects, both traveling at the same speed v, collide as shown to the right. After the collision, the first object travels again with the same speed v, but at a right angle to its initial path. Find the magnitude and direction of the second object’s velocity.
5. [1pt] Consider a perfectly elastic collision between two objects of equal mass. Object 1 is initially moving with a velocity v = 3.07 m/s while object 2 is at rest. What are the final velocities after the collision? Enter the final velocity of object 1 first. Correct, computer gets: 0.002+00 m/s, 3.07e+00 m/s 6.

A block of mass m1 moving with speed v1 undergoes a completely inelastic collision with a stationary block of mass m2. The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3, which is initially stationary. The three blocks then move, stuck together, with speed v3 (Figure 1) . All three blocks have nonzero mass. Assume that the blocks slide without friction.
Two cars of the same mass collide at an intersection. Just before the collision one car is traveling east at 50.0 km/h and the other car is traveling south at 60.0 km/h. If the collision is completely inelastic, so the two cars move as one object after the collision, what is the speed of the cars immediately after the collision? _______ km/h
