- A disk with radius R= 800 m. is spinning about its center. Initially the disc has an angular velocity of 3000 rev/min, and is slowing down uniformly at a rate of 2.0 rad/s 2. By the time it stops spinning, the total number of revolutions the disk will make is: O 11 O 71 39.3 93 3925A Ferris wheel has a radius of 42.4 feet. The bottom of the Ferris wheel sits 0.8 feet above the ground. You board the Ferris wheel at the 6 o'clock position and rotate counter- clockwise. a. Define a function, f that gives your height above the ground (in feet) in terms of the angle of rotation (measured in radians) you have swept out from the 6 o'clock position, a f(a)-42.4sin(a)+43.2 Preview b.

I know that disk A has a mass per unit area o given by o = disk B has o = 3r3. Each disk has radius 10cm. I have a slope at angle 45 degrees to the horizontal that is 2 m long. I time with a stop watch how long it takes the disks to roll down the slope without slipping. (Assuming that the disk's are let go with zero velocity at the top of the slope). a) Calculate the mass of each disk. [4 marks]
- m. Consider the three displacement vectors Ā = (3ỉ – 3 j) m, Ẻ = (i − 4j) m, Ċ = (−21+5j) Use the component method to determine (a) the magnitude and direction of D = Ã + B + Č and (b) the magnitude and direction of Ď = −Ā – B + Č. Express the direction in terms of the angle relative to the positive x axis.1. You are to program a robotic arm on an assembly line to move in the xy-plane. Its first displacement is A; its second displacement is B, of magnitude 10.00 cm and direction 74.2 deg measured in the sense from the +x-axis toward the -y-axis. The resultant C = A + B of the two displacement s should also have a magnitude of 10.00 cm, but a direction 41.6 deg measured in the sense from the +x-axis toward the +y-axis. (a) Find the magnitude of A. 2. A ball is speeding up along a circular track. What can be said about the velocity and acceleration vectors on the body? 3. In an intersection, a bus moving at (100i) m/s and a truck moving at (200j) m/s collided with each other. Assuming that the two objects have the same mass, what would be their final speed together?Pls help ASAP
