Question

Point A moves uniformly with velocity v so that the vector v is continually “aimed” at point B which in its turn moves ... L. How soon will the points converge?

AC is alternating current and DC is direct current. There is a change in direction in the flow of current but for DC there is no such change in direction.

So the problem here given is about a ball which is kicked at an angle $\theta$. Which is moving with a velocity 50 m/s and reaches a horizontal distance 250 m. We have to find the value of $\theta$.
It is having the velocity of $\sqrt{3\ gr}$ at the highest point, we have to find the ratio of tensions in the spring at the hi... (More)
