Two fun-loving otters are sliding toward each other on a muddy (and hence frictionless) horizontal surface. One of them, of mass 8.00 kg , is sliding to the left at 5.00 m/s , while the other, of mass 5.65 kg , is slipping to the right at 5.00 m/s . They hold fast to each other after they collide.
Find the magnitude of the velocity of these free-spirited otters right after they collide..
How much mechanical energy dissipates during this play?

Two boys are sliding toward each other on a frictionless, ice-covered parking lot. Jacob, mass 45 kg, is gliding to the right at 8.02 m/s, and Ethan, mass 31.0 kg, is gliding to the left at 10.5 m/s along the same line. When they meet, they grab each other and hang on. (a) What is their velocity immediately thereafter? b) What fraction of their original kinetic energy is still mechanical energy after their collision? (c) That was so much fun...
Two blocks are sliding across a horizontal frictionless tabletop. Block A has a mass of 5 kg, and it is sliding directly southward with a speed of 8 m/s. Block B has a mass of 7 kg, and it is sliding directly westward with a speed of 4 m/s. The blocks then collide and stick together. What is the speed of the new combined block after the collision?

Two boxes are sliding to the right on a horizontal frictionless surface. Box 1 is trailing box 2. Box 1 has a mass of 2 kg and a speed of 5 m/s, while box 2 has a mass of 4 kg and a speed of 3 m/s. Eventually, box 1 catches up to box 2 and experiences a completely inelastic collision with box 2. What is the speed of the two blocks after the collision?
Consider two masses sliding across a frictionless surface about to undergo a head-on collision as shown in the figure. The first mass (m1 =3 kg) is travelling to the right with a speed of v1 = 8 m/s. The speed of the second mass (m2 = 5 kg) is unknown. After the masses collide, ma rebounds moving off at a speed of v = 2 m/s in the opposite direction, while mz is motionless. a)(10 pts.) At what velocity, v2...

6. Two football players run towards each other and collide on a slick, muddy field. Assuming that player A has mass of 85 kg and speed of 7 m/s and player B has mass of 75 kg and speed of 7.5 m/s, what happens right after they collide (and stick together)? 8. A red cart collides with a blue cart on a rough surface. Which forces acting on the blue cart are internal, if the system is red cart +...
A 4kg mess kit sliding on a frictionless horizontal surface, explodes into two 2 kg pieces. After the collision one part moves towards North with speed of 3 m/s and the other moves at 5 m/s in a direction 30° south of east. Determine the original velocity of the mess kit.
On a frictionless horizontal air table, puck A (with mass 0.248 kg ) is moving toward puck B (with mass 0.369 kg ), which is initially at rest. After the collision, puck A has velocity 0.123 m/s to the left, and puck B has velocity 0.647 m/s to the right.
A block of mass 2.0 kg sliding on a horizontal frictionless surface is attached to one end of a horizontal spring (k = 800 N/m) which has its other end fixed. If the speed of the block as it passes through the equilibrium position is 4.0 m/s, what is its speed when it is a distance of 10 cm from the equilibrium position? a) 3.2 m/s b) 3.5 m/s c) 2.9 m/s d) 2.4 m/s
