Can you help me solve this problem? I really don't know what to do.
The endpoints of a movable rod of length 1 meter have coordinates (x,0) and (0,y). The position of the end on the x-axis is x(t)= (3/5) sin (pi*t) where t is time in seconds.
a) Find the time of 1 complete cycle of the rod.
b) What is the lowest point reached by the end of the rod on the y-axis?
c) Find the speed of the y-axis endpoint when the x-axis endpoint is (3/10, 0)
