ion Image for A heavy flywheel is accelerated (rotationally) by a motor that provides constant torque and therefore a consta. The flywheel is assumed to be at rest at timet = 0 in Parts A and B of this problem.a) Find the time t_1 it takes to accelerate the flywheel to omega_1 if the angular acceleration is Image for A heavy flywheel is accelerated (rotationally) by a motor that provides constant torque and therefore a consta.Express your answer in terms ofomega_1 and Image for A heavy flywheel is accelerated (rotationally) by a motor that provides constant torque and therefore a consta.b) Find the angle theta_1 through which the flywheel will have turned during thetime it takes for it to accelerate from rest up to angular velocityomega_1.Express your answer in terms of someor all of the following: omega_1, Image for A heavy flywheel is accelerated (rotationally) by a motor that provides constant torque and therefore a consta, and t_1.Find the angle theta_1 through which the flywheel will have turned during thetime it takes for it to accelerate from rest up to angular velocityomega_1.Express your answer in terms of someor all of the following: omega_1, Image for A heavy flywheel is accelerated (rotationally) by a motor that provides constant torque and therefore a consta, and t_1.c) Assume that the motor has accelerated thewheel up to an angular velocity omega_1 with angular acceleration Image for A heavy flywheel is accelerated (rotationally) by a motor that provides constant torque and therefore a consta in time t_1. At this point, the motor is turned off and a brake isapplied that decelerates the wheel with a constant angularacceleration of -5. Find t_2, the time it will take the wheel to stop after the brakeis applied (that is, the time for the wheel to reach zero angularvelocity).Express your answer in terms of someor all of the following: omega_1, Image for A heavy flywheel is accelerated (rotationally) by a motor that provides constant torque and therefore a consta, and t_1.

Explanation:
electric field due to non conducting sheet is
the force acting on the piece of Styrofoam
Eq= mg
⇒E= mg/q
now,
⇒
