An astroid of mass 2.1 x 10^15 kg splits apart. Asume the original astroid was at rest.
a) what was the intioal momentum of the system?
b) If the astroid breaks into a first piece moving (-31 m/s) x and the second has a mass of 1.8 x 10^15, in which direction do you expect the second peice to move. Explain
c) what is the final velocity of the larger piece after the break?
What was the power of the motor that kept the wheel rotating at 6.5 rev/hr in spite of friction.
A student wearing frictionless in-line skades on a horizontal surface is pushed by a friend with a constant force of 23.00N. How far should the student be pushed, starting from rest, so that her final kinetic energy is 283J.
A professor's office door is 0.80 wide, 3.0 high, and 5.0 thick; has the mass of 25; and pivots on frictionless hinges. A "door closer" is attached to the door and the top of door frame.
Compared to an object that does not roll, other than instead slides without friction, should a rolling object be released from same, a greater, or a lesser height in order just barely to complete the loop the loop.
A hollow spherical shell has mass 8.00 and radius 0.225. It is originally at rest and then rotates about a stationary axis that lies along a diameter with the constant acceleration of 0.905. What is the kinetic energy of the shell after it has turned..
A rocket has an initial mass of 28,000 kg, of which 20 percent is the payload. It burns fuel at a rate of 185 kg/s and exhausts its gas at a relative speed of 1.8 km/s.
A 40 percent efficient electric power plant produces 900MW of electric power and discharges waste heat into 30 C ocean water. Suppose the waste heat could be used to heat homes during the winter instead of being discharged into the ocean. A typical A..

An infinitely long line of charge has a linear charge density of 5.50×10-12 C/m. A proton is at distance 17.5 cm from the line and is moving directly toward line with speed 2900 m/s.
Sketch a force diagram for the desk.
A race car can be slowed with a steady acceleration of -11 m/s2 if the car is going 55m/s how many meters would it travel before it stops.
