An object moves along a straight track from the point (4,−4,1) to the point (6,6,−7). The only force acting on it is a constant F=−5i−5j+4k newtons. Find the work done in joules if the distance is measured in meters.

Expert Solution

As given an object moves along a straight track from the point (4,−4,1) to the point (6,6,−7) hence we can say that displacement vector is given by,

The only force acting on it is a constant F=−5i−5j+4k newtons hence we can say that we have,

we can write work done is given by,

As force is in newtons and distance is in meters we can write,

we know that 1 newton-meter = 1 joule hence we can write work done is given by,

PART 1: A train moves with constant velocity down a straight track that passes through a tunnel. When the train is at rest with respect to the tunnel, the train is exactly the same length as the tunnel. However, the train in this case is moving relative to the tunnel at nearly the speed of light. The engineer on the train says: “The tunnel is Lorentz-contracted and is shorter than the train; therefore at no time can the train be...
