The _________________ of the car indicates how fast the car moves and the direction of the motion at each instant of time.Question 24Select one:a.Average Velocityb.Instantaneous Speedc.Average Speedd.Instantaneous Velocity

To find the average speed of an object, we find the change in the distance divided by the time over which that change occurs. For the instantaneous speed, we must make the time interval very , so that the speed does not change appreciably.

The average velocity and the instantaneous velocity of an object will be the same if _______.Group of answer choicesThe object’s velocity is always positive.The object’s speed is zero.The object’s speed is constant.The object’s acceleration is constant.

A car is moving in the positive direction along a straight highway and accelerates at a constant rate while going from point A to point B. If the acceleration is positive, increasing the speed of the car, when does the position where the average speed equals the instantaneous speed occur during the time interval from A to B? Assume the time interval is T.Select one:a.after T/2 from the start of the intervalb.T/2 from the start of the intervalc.It depends on the speed at the start of the time interval.d.before T/2 from the start of the interval

A car travels from rest with a constant acceleration a for t seconds. What is the average speedof the car for its journey, if the car moves along a straight road?(A) at2/2 (B) 2at2 (c)at/2 (D) None

A car travels at 54 km/hr for first 20 secs , 36 km/hr for next 30 secs and finally 18 km/hr for next 10 secs. Find its average speed.
