Position of an ant (S in metres) moving in YZ plane is given by $S= 2t^2 \hat j + 5 \hat k$ (where t is in second)
Position of an ant (S in metres) moving in YZ plane is given by $S= 2t^2 \hat j + 5 \hat k$ (where t is in second). The magnitude and direction of velocity of the ant at t = 1 s will be : (A) 16 m/s in ydirection (B) 4 m/s in xdirection (C)…
