A stellar object that is at a great distance emits a stream of matter at velocity v towards an observer obliquely, forming an angle θ with the observation line. For the observer the jet appears to have been emitted laterally at speed V.
Show that for certain angles the speed measured by the observer may exceed the speed of light.

V = sin θ (1 / v - cos θ) −1

An object of mass m1 approaches with velocity v1 another object of mass m2, which is at rest, next to a spring having force constant k. The spring is fixed to a wall and m2 can compress the spring. This is one-dim horizontal collision without friction. We consider two collision scenarios, one which is perfectly inelastic, and the other which is elastic. (a) In the first collision case the object m1 strikes m2 and sticks. Moving together, they compress the...

An object is thrown upward with an initial velocity of 32.1 m/s. When the object reaches it maximum height, it is true of the acceleration, a, and the velocity, v, that: both its acceleration and velocity are zero both its acceleration and velocity change sign velocity is equal to zero, but acceleration is not acceleration is equal to zero, but velocity is not None of the above. Please help. Only one answer is true. Please give reason why.
