Please help immediately A uniform stick AB can be balanced on a knife edge 10cm from one end when a weight of 200N is hung from that end .When the knife edge is removed 5cm further from that end, the 200N weight has to be moved to a point 8.75cm from the knife edge to obtain a balance. Find the length of the stick and its weight.

please draw the diagram before solving

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
