The minute hand of a church clock is twice as long as the hour hand. After what time after midnight does the end of minute hand move away from the end of the hour hand at the fastest rate A) 11 minutes past midnight C) 32 minutes past midnight B) 21 minutes past midnight D) 47 minutes past midnight
A clock has a minute hand that is 12cm long. a. What is the angular speed of the minute hand? Give your answer in radians per second. Give an exact answer. (Hint: how long does the minute hand take to make a complete rotation?) b. What is the linear speed of the tip of the minute hand? Give an exact answer in cm per second.
Torque question: An essentially weightless shovel is 120 cm long. Someone holds it horizontally, supporting it with his left hand at the shovel's center of gravity and his right hand 80.0 cm to the right of the c.g. The shovel contains a 20 N rock whose cg is 8 cm to the right of the edge of the shovel. How much force does the person exert down on the handle? Answer is supposed to be 8 N but I'm having...
i tried (i) and got 688 and it was wrong. help please. thank you. 21.-/5 pointsSerPOP4 10.P.064. The hour hand and the minute hand of Big Ben, the Parliament tower clock in London, are 2 m and 4.50 m long and have masses 60.0 kg and 100 kg, respectively. .70 yo 68s (a) Determine the total torque due to the weight of these hands about the axis of rotation when the time reads the following. (Let positive torque correspond to...
An athlete at the gym holds a 2.5 kg steel ball in his hand. His arm is 60 cm long and has a mass of 3.6 kg. Assume the center of mass of the arm is at the geometrical center of the arm. Part A What is the magnitude of the torque about his shoulder due to the weight of the ball and his arm if he holds his arm straight out to his side, parallel to the floor? Part B What is the...

Fresh out of school, you take a job with a small injection-molding shop with two machines (25 ton and 250 ton. On any given shift, there are two workers assigned to each machine one is concerned with setting/loading and unloading while the other packages the final product for shipping. You have been asked to investigate whether you can improve the process, potentially with automation. Having recently re-read The Goal, you are quite aware that adding robots does not necessarily mean...
