The evidence to cite that the Universe is flat.

Question

Uniform Circular motion. 1. Mini Lecture 2. Let the position of a particle be given by: (t) = Rcos (wt)i + Rsin (wt)j 3. Calculate the expression for the velocity vector and show that the velocity vector is tangential to the circumference of the circle. 4. Calculate the expression for the acceleration vector and show that the acceleration vector points radially inward. 5. Calculate the magnitude of the velocity and magnitude of the acceleration, and therefore show that v2 a = R

4. A ball is thrown vertically up, its speed. slowing under the influence of gravity. Suppose (A) we film this motion and play the tape backward (so the tape begins with the ball at its highest point and ends with it reaching the point from which it was released), and (B) we observe the motion of the ball from a frame of reference moving up at the initial speed of the ball. The ball has a downward acceleration g in: a. A and B b. Only A c. Only B d. Neither A nor B
