The first atomic bomb released energy equivalent to20 kilotons of TNT. If 1 ton of TNT releases 4x109 J, how much uranium was consumed through fission in the bomb? Assume208 MeV per fission; 1 MeV = 1.6x10-13 J; 235 g of U has6x1023 atoms. Hint: get the result by dividing theenergy released by the energy per unit mass of uranium.
A wagon is rolling forward on level ground. Friction is negligible. The person sitting in the wagon is holding a rock. The total mass of the wagon, rider, and rock is 96 kg. Find the speed of the wagon after the rock is thrown
A car in stop-and-go traffic starts at rest, moves forward 19 in 8.0 , then comes to rest again. The velocity-versus-time plot for this car is given in the figure. What distance does the car cover in the first 4.0 seconds of it motion?
