Hello I need help on questions 1,2,3. Work would be appreciated if possible thank you so much!

3. [I2 Points] DETAILS SERPSE10 10.5.0P.014. 0/6 Submissions Used MY NOTES ASK YOUR TEACHER The figure below shows, at left, a solid flywheel of radius R = 0.550 m and mass 50.0 kg. Mounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius of r = 0.230 m. The flywheel and pulley assembly are on a frictionless axle. A belt is wrapped around the pulley and connected to an electric motor as shown on the right. The turning motor gives the flywheel and pulley a clockwise angular acceleration of 1.67 rad/52. The tension Tu in the upper (taut) segment of the belt is 175 N. (a) What is the tension (in N) in the lower (slack) segment of the belt? EN (b) what If? You replace the belt with a different one (one slightly longer and looser, but still tight enough that it does not sag). You again turn on the motor so that the flywheel accelerates clockwise. The upper segment of the belt once again has a tension of 175 N, but now the tension in the lower belt is exactly zero. What is the magnitude of the angular acceleration (in rad/52)? Saw 2.

(Assume that the positive direction is counterclockwise.) 10.0 N 12.0 N 9.00 N 1. [-/3 Points] SERPSE1010.4.0P.013. 0/6 Submissions Used ASK YOUR TEACHER (a) The shing pole in the figure below makes an angle of 20.0 with the horizontal. What is the torque exerted by the sh about an axis perpendicular to the page and passing through the angler's hand if the sh pulls on the shing line with a force F = 96 N at an angle 37.0 below the horizontal? The force is applied at a point L = 2.20 m from the angler's hands. (Enter the magnitude in N - m, accurate to at least the nearest integer.) direction (b) what If? To reel in the sh, the angler now pulls back on the fishing rod, increasing the angle it makes with the horizontal to 390. If the fish still applies the same force in the same direction, what is the increase in the torque exerted by the sh about an axis perpendicular to the page and passing through the angler's hand? (Enter the magnitude in N - m.) :iN-m
