coefficient of kinetic friction 2 m, h A bullet of mass m¡ traveling horizontally with speed u hits a block of mass m2 that is originally at rest and becomes embedded in the block. After the collision, the block slides horizontally a distance d on a surface with friction, and then falls off the surface at a height h as shown. The coefficient of kinetic friction between the block and the surface is µk. Assume the collision is nearly instantaneous and all distances are large compared to the size of the block. Neglect air resistance.

In the figure, block 1 of mass m₁ slides from rest along a frictionless ramp from height h=2.5 m and then collides with stationary block 2, which has mass m2 = 3m₁. After the collision, block 2 slides into a region where the coefficient of kinetic friction uk is 0.55 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic? (a) Number (b) Number i Frictionless Unit Unit -Hk

Calculate the final velocity of block S

Treat the collision as elastic.  A moving billiard ball hits an identical (except for color) stationary ball.   After the collision, the orange ball always goes off in the positive x-direction.  The final speeds are v and V.  Calculate the angle θ that the green ball goes off in.  (θ should be positive.) V0 = the initial green body's speed = 6 m/s M = the mass of both balls = 6 kg φ = the incoming green ball's angle = 70o It's always a good idea to check your answer with the momentum-conservation and energy-conservation equations.

A bullet of mass mb is fired horizontally with speed vi at a wooden block of mass mw resting on a frictionless table. The bullet hits the block and becomes completely embedded within it. After the bullet has come to rest relative to the block, the block, with the bullet in it, is traveling at speed uf.

Problem #4: Consider a frictionless track as shown in the figure below. A block of mass m¡ = 4.00 kg is released from A. It makes a head-on elastic collision at B with a block of mass m2 = 20 kg that is initially at rest. Calculate the maximum height too which m¡ rises after the collision. 5.00 m m2 (B

In the figure, block 1 of mass m1 slides from rest along a frictionless ramp from height h and then collides with stationary block 2, which has mass m2 = 3m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction is μk and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic? Express your answer in terms of the variables given and g.

Problem B) An inelastic collision occurs between a particle of mass 1.5 kg moving with an initial velocity of v = (-2i – 1.33 + 0.7k) m/s and another particle of mass 0.8 kg that has an initial velocity of v = (5.6å + 0.53 + 4.3k) m/s. What is the final velocity of the particles in unit vector notation? %3D
