Abus travels north on some busy city streets for 2.5 km, and a trip that takes 9 minutes. at one point in the trip, the bus is stopped at a red light. what is it's instantaneous velocity in m/s? at another point, the bus travels at a constant speed of 18m/s. what is its instantaneous velocity?

Instantaneous velocity at the red light is 0 m/s.

Instantaneous velocity at another point is 18 m/s towards north.

Explanation:

Instantaneous velocity is the velocity of a body at any given moment of time.

It's the current speed and direction in which it acts.

When the bus is at the red light, it is not in motion at that point. So, the instantaneous velocity of the bus is 0 m/s at that moment of time.

Again, at another point, the bus is moving with constant speed of 18 m/s, so the instantaneous velocity is also 18 m/s but with a specified direction as velocity is a vector quantity.

So, the instantaneous velocity when the bus is moving with constant speed is 18 m/s towards north.
