- 5. After subjecting the car design of a sun-powered car to wind tunnel testing, a group of engineer- ing students estimates the tangential component of the car's acceleration will be at = 0.6 -0.002² m/s², where v is the car's velocity in m/s. If the car starts from rest at A, what are the car's veloc- ity and acceleration in terms of normal and tan- gential components when it reaches B? | 200 m 50 m BIf an object is in equilibriuim, the net torque about any arbitrary axis must be zero. A. True B. FalseA 270-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 7.00 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/s? a = Determine the magnitude of the acceleration a of the descending weight. m/s?
