A particle is moving along the x-axis with its
coordinate with the time 't' given be
x(t) = 10 + 8t – 3t². Another particle is moving
the y-axis with its coordinate as a function of
time given by y(t) = 5 – 8t³.
At t = 1s, the speed
of the second particle as measured in the frame
of the first particle is given as . Then v
(in m/s) is ______.
