A ball of mass M is attached to a string of negligible mass that has a length R. The ball moves clockwise in a vertical circle, as shown above. Which of the following is true about the ball-string-Earth system as the ball moves from point 1 to point 2?

Show, using graphical vector addition, that the acceleration vector for an object in uniform circular motion points toward the center of the circular path. Use the factthat acceleration in two or more dimensions is defined as

At the instant shown, the car at A is traveling at 21 m.s¹ around the curve of radius 67 m while its speed is increasing at 4 m.s2. The car at B travels at 2 m.s¹ along the straightaway. UB BOJ pm pm 45° AG VA The relative velocity of A with respect to B is aA/B-25.0 m.s-² Determine the acceleration of the car at B. (put your answer in the cell below)

A car on a highway is heading toward a cloverleaf interchange with a circular curvature or Radius=50 m, traveling at a steady speed of 14m/s. A) determine the position and velocity of the vehicle at points A and B. B) determine the vector components and direction of the average acceleration during the trip from a to b. Include a sketch of the vector showing it's orientation. SPeciffy the direction between -180 degrees and 180 degrees as measured from the +x axis.
