A spaceship is approaching the earth at a relative speed of 0.85c. The mass of the ship is 1.00 X 107 kg. Find the magnitude of each of the following.
(a) the classical momentum of the ship
(b) the relativistic momentum of the ship
An 9.00-cm-diameter, 390g sphere is released from rest at the top of a 1.50-m-long, 15.0 degree incline. find the sphere's angular velocity at the bottom of the incline
Two people are holding up the ends of a 4.75-kg wooden board that is l = 2.00 m long. A m = 3.00-kg box sits on the board, 0.50 m from one end. What forces do the two people exert.
Two children tug on a toy of mass 2.0 kg. Costa pulls with a force of 10.0N [W 30degrees S]. The toy slides with an acceleration of 2.5 m/s^2 in the direction of the net force.
The power P of an Electric circuit varies jointly with resistance , R and with the square of the current, I. find the power if the current is 2.00 A and the resistance is 2.00 ohms
A space station, in the form of a wheel 133 m in diameter, rotates to provide an "artificial gravity" of 2.20 m/s2 for persons who walk around on the inner wall of the outer rim. Find the rate of the wheel's rotation in revolutions per minute that wi..
define How fast is the osprey approaching. Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion.
On a frictionless, horizontal air track, the glider oscillates at the end of an ideal spring of force constant 2.52N/cm. The graph in the acceleration of the glider as a function of time. Find the mass of the glider.
Engineers can determine properties of a structure that is modeled as damped spring oscillator-such as a bridge-by applying a driving force to it, What is the oscillator\'s damping constant? (kg/s)
Calculate the increase in internal kinetic energy (that is, for the ship and the shell). This energy is less than the energy released by the gun powder-significant heat transfer occurs
