A 368 kg car moving at 16.4 m/s hits from behind another car moving at 11.1 m/s in the same direction. If the second car has a mass of 623 kg and a new speed of 12.6 m/s, what is the velocity of the first car after the collision?
Consider three ants each clinging for dear life to the top surface of an ordinary compact disc and not moving with respect to the labelling. The ants are at distances 3, 4, and 5 cm away from the axis of rotation of the CD which is spinning at a cons..
a block of mass m1 = 11 kg is held at the top of a frictionless inclined plane at point A , 6m above the ground. What is the work done on the spring as it is compressed
The yellow light from a helium discharge tube has a wavelength of 587.50. When this light illuminates a certain diffraction grating it produces a first-order principal maximum at an angle of 1.050.
A bullet of mass mB = 0.0149 kg is moving with a speed of 102 m/s when it collides with a rod of mass mR = 7.85 kg and length L= 1.08 m, How much kinetic energy is lost in the collision
Two identical +9.5 uC point charges are initially 3.5cm apart from each other. If they are released at the same instant from rest, how fast will each be moving as they are very far away from each other? Assume they have identical masses of 1 mg.
A ball is thrown off a cliff, 100 meters tall, with an initial velocity of 5.00 m/s, which is purely horizontal direction. How long before the ball hits the ground
