Can an object have a low acceleration and high velocity at the same time. give example

Of course!

A passenger jet, cruising at 37,000 feet on its way to California,

keeping a constant airspeed and flying in a straight line, can have

a velocity of 500 miles per hour west, but its acceleration is zero!

Yes, acceleration only tells you how velocity is changing. It doesn't say anything about what velocity is at any given time.

For example, if you set your car to cruise control on the highway going 80 mph. That is a constant high velocity, yet the car has 0 acceleration.

The opposite is also true. After a red light turns green, you put foot on the gas to accelerate. However, your velocity is initially low even though it has high acceleration.
