The potential at location A is 478 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 1130 V, and when released from rest from this spot, the particle arrives at B with twice the speed it previously had, or 2 vB. Find the potential at B.
A damping force acts on the egg, and the amplitude of the motion decreases to 0.101 in a time of 5.00 compute the magnitude of the damping constant b.
A. The rate of hydrogen fusion (proton-proton chain) near 10^7 K increases with temperature as T^5. If you raise the temperature of the hydrogen-burning core by 10 percent, how much does the hydrogen fusion energy increase?
The work on a system with a mass 100 lbm is known to be 10 BTU's . If there is no change in potential energy and the speed changes from rest to 32 ft/sec. What is the change in the internal energy of the system?
From another measurement, you have found that velocity of the jumper's center of mass has only a y component of v2=2.5 m/s as the jumper's feet leave the floor.
Status Newton's First Law of motion.
An airplane has a mass of 2.6 x10^6 kg, and the air flows past the lower surface of the wings at 95m/s. If the wings have a surface area of 1200m2, how fast should the air flow over the upper surface of the wing if the plane is to stay in the air?..
Illustrate what is the magnitude of the apparent weight of a 78kg astronaut 5200km from the center of the Earth's moon in a space vehicle moving at constant velocity?
A very long non conducting cylinder of diameter 10.0 cm carries charge distributed uniformly over its surface. Each meter of length carries +5.50 C of charge. A proton is released from rest just outside the surface.
Calculate the energy in of a photon of radiation. A projectile is fired straight upward at 141 m/s. How fast is it moving at the the top of its trajectory? assume it is launched upward at 45 degrees about the horizontal plane. How fast is it moving..
how to determine the magnitude of the acceleration at the instant.
An object of mass "m" is thrown up an inclined plane of angle "theta" with an initial velocity "v knot". If the motion is resisted by retarding force Fr=-kv (where k is a force coefficient and v the velocity of the object.)
