ball tied to the end of a string of length 10cm is rotated with constant speed of 2m/s in a circle about the origin. Find the equation of projection of the ball on the x-axis. At t=0, the ball makes an angle of 45° with the x-axis & is travelling in anticlockwise direction. a) 0.1sin(20t + 3π/4) b) 0.1cos(20t + π/4) c) 10sin(20t + π/4) d) 10cos(20t – 3π/4)
