A light string is wrapped around a spool (shape is unknown, thus you do not know moment of inertia I) of radius 0.5 m. A 5.0-kg mass is hung from the string, causing the spool to rotate and the string to unwind. The spool rotates from rest to 10 rad/s in 2 s. Find (a) the angular acceleration of spool, (b) moment of inertia I, and (c) the tension on the string.

a) angular acceleration  α = 5 rad/sec

b) MOI = 1.25 kgm^2

c) Tention in the string T = 12.5 N

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
