A particle is moving along the x -axis with its coordinate with time t given by x t = 10 + 8 t - 3 t 2 . Another particle is moving along the y -axis with its coordinate as a function of time given by y t = 5 - 8 t 3 . At t = 1   s , the speed of the second particle as measured in the frame of the first particle is given as v . Then v i n   m   s - 1 is ___________.

Correct answer

0

Step-by-step solution

v 1 → = 8 - 6 t i ^ v 2 → = - 24 t 2 j ^ v 21 → = 580
