Qn.64 ) Instantaneous speed at t= 2.5 s is 0 m/s
It can be seen that at t = 2.5 s, there is no dispalcement for small time interval Δt .
Qn. 65) During the interval 0 to 5 s, average velocity of cart is 0 m/s .
Average velocity during the given interval is defined as net displacement in that time interval divided by time.
At t= 5 s, the displacement has become zero.
