Two ball, of equal masses mA = 40g and mB = 60g, are suspendedas shown. The lighter ball is pulled away to a 60degree anglewith the vertical and released.
(a) What is the velocity of the lighter ball beforeimpact.
(b) What is the velocity of each ball after the elastic collision?
(c) What will be the maximum height of each ball afterthe elastic collision?
Three forces of magnitudes F1 = 4.0 N, F2 = 6.0 N, F3 = 8.0 N, F4 = 5.0 N, and F5 = 5.0 N are applied to a block of mass m = 3.0 kg, initially at rest, at angles shown on the diagram. (Figure 1) All angles should be measured from the positive x ax..
A particle of mass m is constrained to move between two concentric impermeable spheres of radii r = a and r = b (a
A car is moving with constant velocity v, and has wheels of radius R. At what angle does the piece of mud drop off the wheel
1. A 50.0 kg block is pulled from rest by a force of 1000.0 N at an angle of 37.0° across a horizontal rough surface over a distance of 5.60 m. The coefficient of kinetic friction between the block and the surface is 0.500.
