5. [1pt] Consider a perfectly elastic collision between two objects of equal mass. Object 1 is initially moving with a velocity v = 3.07 m/s while object 2 is at rest. What are the final velocities after the collision? Enter the final velocity of object 1 first. Correct, computer gets: 0.002+00 m/s, 3.07e+00 m/s 6. [1pt] If the objects have masses m = 2.37 kg and m2 = 4.94 kg, what are the final velocities of the objects after the...
Consider two masses: Mi=2.0 kg and M2 =1.5 kg. Mass Mı moves on a horizontal surface where the coefficient of kinetic friction 4k = 0.40. Mass M2 is hanging freely. Two masses are connected by a strong cord of negligible mass that extends over a pulley.

Problem #1 mi m2 Two blocks mı = 4 kg and m2 = 9 kg are initially arranged as shown in the figure. They are tied to a massless rope going around the pulley. The pulley has a form of a cylinder with a mass of M = 8 kg and radius of R = 40 cm. Both the incline and the horizontal surface have a coefficient of kinetic friction ulk = 0.15.

problem 7 (1 point) Two objects of equal masses mA me-1kg are placed on a horizontal rotating disk; their distances from the center are RA - 1 m and Re 4m. The objects are made of different materials, and the coefficients of static friction between the objects and the disk are μ^ and The disk is very slowly increasing the angular speed, so that the angular acceleration is negligible. Both objects start sliding off the disk at the same time...
Problem 5 (15 points) A small bead can slide without friction on a circular hoop that is a vertical plane and has a radius of 0.100 m. The hoop rotates at a constant rate of 4.00 rev/sec (recall 1 rev = 2π rad) about a vertical diameter as shown in the figure below (a) Find the angle β at which the bead is in vertical equilibrium. (It has a radial acceleration toward the axis.) (b) Is it possible for the...

1) Why is there a different equation for elastic vs inelastic collisions? Are they really different? 5) If the first car does not go through either photogate after collision, what will its velocity essentially be? The conservation of momentum is a fundamental law in classical mechanics. It states that the total momentum of a system at the initial condition and ending conditions must be equivalent or p. - P. This can be modeled by studying the effect of objects in...
