In the 1950s, an experimental train that had a mass of 2.50 x 104 kg was powered across a level track by a jet engine that creates a thrust of 5.00 x 105 N for a distance of 509 m.
1. Discover the work done on the train.
2. Discover the change in kinetic energy.
3. Find the final speed of the train if there were no friction.
4. Find the final kinetic energy of the train if it started from rest.
You have a battery marked 6.00 V.When you draw a current of 0.245 A from it, the potential difference between its terminals is 5.13 V
In an oscillating series RLC circuit, find the time required for the maximum energy present in the capacitor during anoscillation to fall to half its initial value. Assume q =Q at t = 0. (Use R, L,C, and Q, as necessary, where all quantities arein SI..
A 10.0 kg block is dragged overa rough, horizontal surface by a 73.0 N force acting at 20.0° above thehorizontal. The block is displaced 4.50 m, and the coefficient of kinetic friction is 0.300.
The tip of a scanning electron microscope has a radius ofcurvature of 5 nm, and is at a potential of 3V. estimate the electric field at its surface
An explosion breaks an object into two pieces, one of which has 1.60 times the mass of the other. If 8000 J were released in the explosion, how much kinetic energy did each piece acquire? Heavier piece
