A string is wrapped around the central axis of a platform that's free to rotate. A 100g mass attached to the string falls, exerting a torque on the spinning platform. The empty platform has a rotational inertia of 1.75g*m^2. Two masses, m1 = 25g and m2= 35g, are attached to the top of the platform a distance of 15cm from the central axis. Once the 100g mass falls a distance of 1.31m, the string detaches from the central axis. At this point the 100g mass is moving downward at a speed of 0.96m/s. Find the maximum rotational speed of the rotating platform with masses m1 and m2 attached.

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
