coordinate with the time 't' given be

x(t) = 10 + 8t – 3t

At t = 1s, the speed of the second particle as measured in the frame of the first particle is given as $$\sqrt v $$. Then v (in m/s) is ______.

x(t) = 10 + 8t – 3t

^{2}. Another particle is moving the y-axis with its coordinate as a function of time given by y(t) = 5 – 8t^{3}.At t = 1s, the speed of the second particle as measured in the frame of the first particle is given as $$\sqrt v $$. Then v (in m/s) is ______.
