Question

Using the quantities for rotational motion, write an equation that describes spinning motion of an object, for example, a record player, merry-go-round, or a rotating table in your home: a. For an object rotating at a steady speed 2. b. For an object speeding up at a steady rate c. For an object slowing down at a stcady rate

Answer 1

​​​​​Here are the answers attached of the respective question with assumed standard variables.

Let as sum record player merry go round, rotating table All have same application of Rotational motion object rotating at steady speed Let that steady speed a w rad/sa Let Q be tangle traversed (rad) [Q = wt] speeding up at steady rate Let steady rate by alpha rad/s^2 [Q = wt + 1/2 alpha t^2] If slowing down at steady rate Let this steady rate be lambda rad/s^2 Q = wt + 1/2 (- lambda) t^2 [Q = wt -1/2 lambda t^2]
