- PROBLEM 4: Solid spheres A and B with both of each mass of 2 kgs undergo a direct central impact. Before impact, A is moving to the right with a velocity of 4 m/s and B is stationary. Determine the velocity of A after impact if the impact is perfectly plastic.arrow_forwardA cube measuring bxbxb with a mass, m lies on a horzontal flat surface. The cube is subjected to the force of gravity and the friction coefficient between the cube abd the surface, mu. If the cube is sliding without rotation, and the impulse, L is given, find the distance the cube travels using the impulse-momentum and work-energy principles.arrow_forwardThe two disks moving along parallel paths collide with the velocities shown. The radius of A is 50 mm, and its mass is 0.4 kg. Disk B has a radius of 100mm and a mass of 0.8 kg. Determine the speed of each disk immediately after the impact if the coefficient of restitution is 0.7. Neglect frictionarrow_forward
- Two stars each of one solar mass (= 2×1030 kg) are approaching each other for a head on collision. When they are a distance 109 km, their speeds are negligible. What is the speed with which they collide ? The radius of each star is 104 km. Assume the stars to remain undistorted until they collide. (Use the known value of G)arrow_forwardA 3.0 kg mass is released from rest at point A of a circular frictionless track of radius 0.40 m, as shown in the figure. The mass slides down the track and collides with a 1.4 kg mass that is initially at rest on a horizontal frictionless surface. If the masses stick together, what is their speed after the collision? Notes: the angle in the figure is 90 degrees and point A is on the right side. v shows the direction that the mass will move after being released. Options: 2.1 m/s 2.5 m/s 1.9 m/s 2.3 m/s 1.7 m/s 1.5 m/sarrow_forwardConsider the sun and its largest planet Jupiter. On the line joining them, how far from the center of the sun os their center of mass? Is it within or outside the sun? (Jupiter-sun distance is 778 x 106 km, diameter of the sun is 1.4 x 106 km, the sun is 1000 times as massive as Jupiter.)arrow_forward
- A solid sphere of mass, M = 5.0 kg, and radius, R = 0.100 m is placed on two blocks so that it’s centre of mass lies at the origin as shown on the right. A bullet of mass, m = 0.100 kg, and with an x coordinate of b = 0.04 m strikes the sphere from below with a vertical velocity, v = 65 m/s and embeds in the sphere coming to rest at the location (-b,0) in the diagram below. Since there is no momentum in the horizontal direction, after the bullet hits the sphere , it will rise up to some maximum height and then fall back to its initial position on the two blocks. While the sphere is in the air it will rotate. What is the magnitude of the angle (in degrees) through which the sphere will rotate before it makes contact with the two blocks again?arrow_forwardPlease include a Momentum-Impulse diagram.arrow_forwardA ring (2 kg, r = 1 m) rotates in a CW direction with initial angular velocity 20 s-1. A disk (4 kg, r = 1 m) rotates in a CCW direction with initial angular velocity 50 s-1. The ring and disk "collide" and eventually rotate together. Assume that positive angular momentum and angular velocity values correspond to rotation in the CCW direction.What is the initial angular momentum Li of the ring+disk system? kg m2 s-1 What is the final angular velocity ωf of the ring+disk system? s^-1arrow_forward
- A uniform circular disk of radius R = 36 cm has a hole cut out of it with radius r = 16 cm. The edge of the hole touches the center of the circular disk. The disk has uniform area density σ. The horizontal center of mass of the disk with hole will be located: Write a symbolic equation for the total mass of the disk with the hole. Write an equation for the horizontal center of mass of the disk with the hole as measured from the center of the disk. Calculate the numeric position of the center of mass of the disk with hole from the center of the disk in cm.arrow_forwardA rod 2 meters long has a linear density of p(x) = 8 - 3x. How far, in meters, is the center of mass of the rod if measured from the left?arrow_forwardWhat are (a) the x coordinate and (b) the y coordinate of the center of mass for the uniform plate shown in the figure if L = 19 cm?arrow_forward
