4) Draw a straight horizontal line of length πD from point P at the contact surface of circle and ground . 5) Divide the line into 12 equal parts 1’, 2’, 3’…..12’ (same no. as that of circle). 6) Draw again a circle of 50 mm diameter at πD distance with centre C’. 7) Draw horizontal and vertical axis for 2nd circle.
A solid disk is rolling without slipping along a horizontal surface with a speed of 4.50 m/s when it starts up a ramp that makes an angle of 25.0° with the horizontal. What is the speed of the disk after it has rolled 3.00 m up the ramp? A) 4.01 m/s B) 1.92 m/s C) 2.06 m/s D) 6.79 m/s E) 8.02 m/s
