Question

Question 7 is related to the force vs mass graph that is provided and the first section of the excel sheet. Question 3 has to do with the force bs acceleration graph and second section of the excel sheet. The first two files are showing the equations that are supposed to be used to find these answers. Any help would be greatly appreciated.

LAB & CIRCULAR MOTION PART 1, NEWTON'S 2ND LAW For a particle that undergoes uniform circular motion, at each instant of time the acceleration, a and the velocity, 1 of the particle are at right angles to each other. The velocity, 8, is always tangent to the circular path in the direction of the motion of the particle, while the acceleration, a is always directed radially inward, in the direction of the change in the motion of the particle. The acceleration of a particle that undergoes uniform circular motion is called centripetal ("center- seeking") acceleration The magnitude of the centripetal acceleration is given by 12 (1) R 4 = R2 where R is the radius of the circular path, v is the speed of the particle, and is the angular speed Figure 1 of the particle about an axis that passes at right angles through the center of the circular path. Newton's Second Law states that the vector sum of all the forces exerted on a particle causes the motion of the particle to change in a predictable way. In other words, a net force on a particle causes the particle to accelerate. (In physics, acceleration not only means to speed up, but also to slow down and to change direction) Fset = = ma (2) In addition, Newton's Second Law states that the change in the motion of the particle, not necessarily the motion itself, is in the direction of the net force, that is, the acceleration is in the direction of the net force on the particle.

I mainly need assistance on number 1 and 2 now. The question with the free body diagram and Newtons 2nd Law. We are talking about centripetal motion.
