Figure one show a car Evening towed at a steady speed up a slope which is inclined at 5 degree to the horizontal. Assume that the resistive forces acting on car A are negligible. car A has a mass ...

A 1kg block is at rest on the floor while a rope is pulling on it applying a force of 5N at an angle of 30 degrees above the horizontal. What is the magnitude and direction of the normal force ...

Hi, my parents are renovating and wanted to throw away a bunch of old smoke always and old gas lantern mantles we had in the attic! I made a breeder reactor and I now have plutonium. Can I sell ...

I mean, it would somehow add or remove electrons from any atom and combine them, creating anything (cars, food, water etc.)

I have understood that voltage is how much energy is carried by the current but say you had current of 10A carrying 20V, does that mean amp of current is carrying 20V or does that mean that the ...

Scientists in Asia and the Middle East seem to be more interested in experimental and quantum physics. Things that have current commercial application. Whites seem obsessed with the stream of physics that involve spacetime. Even at an undergraduate level, ...

1. A physcis student throws a ball straight up into the air with a speed of 17.5 m/s. The ball is in the air for a total of 3.60s before it is caught at its original position. ...

Find the car’s kinetic energy, KE. The work needed to bring it to a stop will be -KE. This assumes the braking force is the only force acting on the car in the direction it is traveling.

Velocity V(t) = V(0) + a*t = 5 + 20*10 = 205m/s at t = 10s

The barrel of a rifle has a length of 0.955 m. A bullet leaves the muzzle of a rifle with a speed of 615 m/s. What is the acceleration of the bullet while in the barrel? A ...
