Question 1 Your electric drill rotates initially at 5.35 rad/s. You slide the speed control and cause the drill to undergo constant angular acceleration of 0.345 rad/s for 4.59 s. What is the drill's angular displacement during that time interval? angular displacement: rad Question 2 A flywheel in the form of a uniformly thick disk of radius 1.03 m has a mass of 90.6 kg and spins counterclockwise at 257 rpm. If the positive direction of rotation is counterclockwise. calculate the constant torque r required to stop it in 1.25 min. 1 = N.m Question 3 A pair of constant forces of magnitude F = 15.9 N is applied to opposite sides of the axle of a top, as shown in the figure. The diameter of the axle is d = 8.31 mm. The angle 0, which has a value of 31.3', describes the steepness of the top's - - -'1- - sloping sides. The moment of inertia of the top about its spin axis is / = 0.747 kg.m . What is the tangential acceleration d at of the point labeled P, which is at a height of h = 4.75 cm above the floor? R P at cm/$2 Frictionless floorQuestion 4 The Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. Approximate the pulleyr as a uniform disk with mass mp = 5. [3 kg and radius r? = 0.350 m. The hanging masses are mL = 1?.1 kg and an\" = I29 kg. Calculate the magnitude of die masses' acceleration a and the tension in the left and right ends of the rope, TL and TR, respectively. Question 5 A 240-g mass hangs from a string that is wrapped around a pulley, as shown in the figure. The pulley is suspended in such a way that it can rotate freely. When the mass is released, it accelerates toward the floor as the string unwinds. Model the pulley as a uniform solid cylinder of mass 1.00 kg and radius 5.00 cm. Assume that the thread has negligible mass and does not slip or stretch as it unwinds. Determine the magnitude a of the pulley's angular acceleration. rad/$2 Determine the magnitude of the acceleration a of the descending weight. m/s2 Calculate the magnitude of the tension 7 in the string.
