(2) A block of mass m = 2kg, slides on a horizontal surface and collides with a spring of force constant 200N/cm. The block compresses the spring 6.16cm from the un-stretched position. Mechanical energy in the amount of 200m) is dissipated due to friction as the block is brought to rest. What was the speed of the block at the instant of collision with the spring? (5-points)

On a frictionless surface. a block of mass M moving at speed v collides elastically with another block of the same mass that is initially at rest. After the collision, the first block moves at an angle θ to its initial direction and has a speed U/2. The second block's speed after the collision is 3 4 (B) 2 2 U) (E) ut cose

A block of mass m1 = 1.4 kg initially moving to the right with a speed of 3.0 m/s on a frictionless, horizontal track collides with a spring attached to a second block of mass m2 = 2.5 kg initially moving to the left with a speed of 1.8 m/s. The spring constant is 565N/m. What if m1 is initially moving at 3.2 m/s while m2 is initially at rest? (a) Find the maximum spring compression in this case. (b)...

15. A car of mass m moving at a speed v, collides and couples with the back of a truck of mass 2m moving initially in the same direction as the car at a lower speed v. (a) What is the speed v, of the two vehicles immediately after the collision? (b) What is the change in kinetic energy of the car-truck system in the collision?
Mass m = 0.1 kg moves to the right with speed v=0.64 m/s and collides with...
Mass m = 0.1 kg moves to the right with speed v=0.64 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction = 0.82 of its original kinetic energy. What is the speed VR (in m/s) of the mass which was originally at rest before the collision? Hints: All motion is in 1D. Ignore friction between the masses and the horizontal surface. You will probably need to use the quadratic formula...

Block A of mass, mA = 1.7 kg is shot from a spring device of spring constant, k = 700 N/m along a frictionless horizontal surface. The initial compression of the spring is 0.300 m. The shot makes the block rise to another horizontal level at a height h= 1m above the first. On this horizontal it collides with another stationary block B of mass mB = 3.5 kg. The blocks stick together and encounter a rough surface. The blocks...

A block of mass m -2.00 kg collides head on with a block of mass m- 10.0 kg initially at rest on a rough horizontal surface. The block m strikes m2 with a speed of 4.00 m/s. Immediately after the very brief inelastic collision, the 2.00 kg block bounces back with a speed of 1.20 m/s. Ignore the effect of friction during the collision. (a) 4pts.] Calculate the speed of the 10.0 kg block immediately after the collision. (b) 4...

Block B of mass 10.0 kg is placed in contact with an unstretched spring on a horizontal, frictionless surface. The other end of the spring is attached to a fixed support. Block A with a mass of 4.00 kg is moving with a speed of 20.0 m/s when it collides with and sticks to B. (a) What is the speed of the combined blocks after the collision? The blocks compress the spring 2.60 m before coming to rest momentarily. (b)...

6. Consider a horizontal spring with spring constant k. A block with mass m is pushed far to the left against the spring until the spring is compressed a distance r relative to its relaxed length. A second block, which is stationary and also has a mass m, is located to the right of the spring im rrm a) We release the first block from rest. Due to the force from the spring, it slides to the right and eventually...
