MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A 8.20-kg hanging object is connected by a light, inextensible cord over a light, frictionless pulley to a 5.00-kg block that is sliding on a flat table. Taking the coefficient of kinetic friction as 0.247, find the tension in the string. (The block slides to the right in the diagram below.) N m mo Need Help? Read It Watch It Submit Answer8.

O The tensions in the both cords will remain the same. The tension in the left cord will increase while the tension in the right cord will decrease. O The tension in the left cord will decrease while the tension in the right cord will increase. Explain.9. [8/16 Points] DETAILS PREVIOUS ANSWERS SERPSE10 5.8.P.034. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A block of mass 2.00 kg is pushed up against a wall by a force P that makes an angle of 0 = 50.0 angle with the horizontal as shown below. The coefficient of static friction between the block and the wall is 0.290. (a) Determine the possible values for the magnitude of P that allow the block to remain stationary.
