Task 3 is due on Tuesday, 10/10/2017 by 3pm Something different happened on Harry on the rooftop. He tried to jump off after Aziz, but betrayed him by making a sharp stop right at the roof edge and threw him off the moment at the roof edge, the horse lowered its front body and Harry was holding the rein tightly. Let's simplify Harry's off-horse motion (J→Q→K) as illustrated in Figure 2: one end of the rein was tethered to the roof edge E, and the distance between E and Harry's center of mass was maintained at r3 meters. Harry was simplified as a particle. a. Define which type of motion it is for Harry's off-horse his horse horseback. At that Figure 2: Harry's off-horse Path. motion (J-Q>K). Set s along the circular path J→Q→K with the origin at J. velocity is given as v = 5+1 . Derive a formula for v as a function of angle θ ; θ is defined in Figure 2, and has a unit of radian. Also determine the velocity at which the poor Harry hit the sidewall of the building (at point K). b. At 1 = 0, s-0. Harry's tangential tangential acceleration q, and normal acceleration a, as a function of overall acceleration (both magnitude and direction) at points Q and K. Then determine Harry's
