No
it is bcoz in a straight line motion when the magnitude of speed is zero,then with or without considering its direction,velocity will be zero only

Answer:
No. It is not possible for an object to have 0 speed but non-zero velocity. It is because in a straight line motion when the magnitude of speed is zero, then with or without considering its direction , velocity will be zero only.
It can be proved as in the following.
Speed = Distance / time. = 0
Hence distance covered = 0
Therefore Displacement is also 0.
And hence Velocity = displacement / time = 0.
Therefore when speed is zero velocity is always zero. Hence its not possible.
