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.)

In the figure below, block-2 of mass M = 1 Kg is at rest on a frictionless surface and touching the end of an un-stretched spring whose spring constant is 200 N/m. The other end of the spring is fixed to a wall. Block-1 of mass 2 Kg, travelling at speed v_1 = 4 m/s, collides with block-2 and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?

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 24 m/s. The masses of the two objects are 2.9 and 7.9 kg Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is...

Block 1, of mass m1m1m_1 = 6.70 kgkg , moves along a frictionless air track with speed v1v1v_1 = 27.0 m/sm/s . It collides with block 2, of mass m2m2m_2 = 57.0 kgkg , which was initially at rest. The blocks stick together after the collision. (Figure 1) Figure 1 of 1The figure shows two states of a system of two blocks, labeled 1 and 2, of masses m 1 and m 2, respectively. Block 2 is to the right...

Block 1, of mass m1 = 8.90 kg , moves along a frictionless air track with speed v1 = 31.0 m/s . It collides with block 2, of mass m2 = 15.0 kg , which was initially at rest. The blocks stick together after the collision. (Figure 1) What is the change ΔK=Kfinal−Kinitial in the two-block system's kinetic energy due to the collision?

2. Mass mi 10.0 kg is initially held against the spring of spring constant k 100 N/m. The spring is compressed a distance x 0.45 m. When released, m, is fired towards a block of mass m 4.4 kg initially at rest at the edge of a horizontal, frictionless table of height h- 0.75 m. A ramp is placed at the end of the table. The ramp has a coefficient of kinetic friction μ-0.25 and is a distance d...
