Two objects with masses represented by m1 and m2 are moving such that their combined total momentum has a magnitude of 18.5 kg · m/s and points in a direction 71.5°above the positive x-axis. Object m1 is moving in the x direction with a speed of v1 = 2.75 m/s and m2 is moving in the y direction with a speed of v2 = 3.22 m/s. Determine the mass of each object in kilograms. m1= kg m2= kg
A light, rigid rod of length l = 1.00 m joins two particles, with masses m1 = 4.00 kg and m2 = 3.00 kg, at its ends. The combination rotates in the xy plane about a pivot through the center of the rod (see figure below). Determine the angular momentum of the system about the origin when the speed of each particle is 3.20 m/s. magnitude kg · m2/s direction chose the right one ( +x , -x , +y...
Three Velcro blocks, i.e Velcro on their ends, are shown below. The masses and velocities of the blocks are m1 = 7.6 kg, v, = 11.0 m/s. m2 = 10.0 kg, v2 = 4.0 m/s and m3 = 4.0 kg, v3 = 2.0 m/s.

You have two equal masses m1 and m2 and a spring with a spring constant k. The mass m1 is connected to the spring and placed on a frictionless horizontal surface at the relaxed position of the spring. You then hang mass m2, connected to mass m1 by a massless cord, over a pulley at the edge of the horizontal surface. When the entire system comes to rest in the equilibrium position, the spring is stretched an amount d1 as shown...
