1. A projectile motion over a circle with radius r becomes tangent with the circle at 45 degrees. What is the velocity at its highest point/
2. Constant acceleration and energy
3. The angle between the tangent points and the topmost point at the center of the circle is 45 degrees. If the initial velocity is v_i, the tangent velocity is v and the topmost velocity is v_t I know the following: In the x direction all these velocities are equal. Both components of the middle velocity are equal. This is also the total velocity of the highest point. The height of the tangent point is r+rcos45. The height from the tangent to the topmost point is rsin45. The topmost height from the bottom is r+ 2rsin45. Where do I go from here?
