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 folowing.
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.
.
But the opposite is possible. A particle may hav non-zero speed with zero velocity. that is because of the displacement may be zero but distance covered need not be zero.
mark it breanliest pleeeeaseeeee.

Answer:
hi, here is your answer! !!!!★ ★ ★ ★ ★
No because in a straight line motion distance and displacement are same so the velocity and speed will be same
