Calculate the energy content of 1 kg of natural uranium assuming complete fission. Estimate an average energy per fission. Compare this to the energy in 1 kg of coal (reference all values assumed). Why is this estimate of the energy content of 1 kg of uranium somewhat misleading when we consider the current "once through" fuel cycle that exists in the US? What is the energy content in the roughly 64,000 tonne of used fuel in the US and the roughly 800,000 tonne of depleted uranium in the US (again assuming complete fission of each of these)?
A cricket ball is bowled at a speed of 144 km/hr. suppose the ball diameter is 70 mm and a drag coefficient 0.45, estimate the drag force in newtons which would be acting on the ball.
A 40-g object connected to a spring with a force constant of 30 N/m oscillates with an amplitude of 8 cm on a frictionless, horizontal surface. Find the total energy of the system
A positive charge, Q = 45 is placed on the x-axis at x = -1.9 cm. A positive charge which is twice as large is brought from infinity to a point x = +1.9 cm on the x-axis. what would be the speed of the 2*(45) charge at infinity

A baseball (m = 155 g) approaches a bat horizontally at the speed of 40.5 m/s (91 mi/h) and is hit straight back at a speed of 45.5 m/s (102 mi/h).
Suppose you have an electric hot water heater for your house which is an aluminum cylinder which has a 0.44 m radius and is 1.8 m high. The walls are 1.0 cm thick.
A flagpole of length 9 m and mass 35 kg is hinged at one end, where it is connected to a wall as sketched below. The pole is held up by a cable attached to the end. Find out the tension in the cable. (Assume the flagpole has an uniform mass distr..
