Answer:
4 times
Explanation: since we have been given x-t (displacement time graph) therefore as we know that slope of x-t curve gives velocity and thus the number of Maxima and minima on x-t graph determine when the velocity becomes zero so from the graph we get 2 Maxima and 2 minima
Thus velocity is zero for "4 times"
Thank you!
