pleaaase helpp Exercise 2 (5 points) Two objects A and B move in the same direction with constant speed on a rectilinear track, modeled by the axis Ox. Obje A passes by the point O (the origin of the axis) at an instant t = 0, with a speed of A = 25 m.s. Object 8 passes by point C which if far away from point O by a distance of 500 m at an instant t=0s with a speed of vy = 15 m.st. 1. What is the nature of the motion of the objects? 2. Determine x,(t) the parametric equation of motion of object A. 3. Determine xa(t) the parametric equation of motion of object B. 4. Calculate the instant te where object B will catch up object A. 5. Calculate the location x, where object B will catch up object A. Exercise 3 (4 points) A disk or radius R = 17 cm rotates at 2000 rpm (rounds per minute) Calculate N the frequency of rotation of the disk. Calculate T the period of rotation. 3. Calculate V the speed of the disk. 4. Calculate "n" the number of rounds made by the disk in 30 s. 1. 2.
