A train travels from one station to another station at a speed of 40 kmph and returns to the first station at a speed of 60kmph. calculate the average speed and average velocity of the train?

average speed = S1+S2/2 here s1 = 40kmph s2 = 60kmph Average speed = 40+60/2 100/2 = 50 kmph


Can a body have nonzero average speed but have zero average velocity give example?

Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.

What is the acceleration of a car that travels in a straight line at a constant speed of 110 km h?

The acceleration of an object that travels in a constant straight line velocity is zero.


What happens to an objects speed if it travels with constant acceleration?

If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.


What is the acceleration of a car that travels in a straight line at a constant speed of 135 kilometers per hour?

If a car travels in a straight line with a constant speed, then the car has a constant velocity (determined by direction and speed), and the acceleration is 0.
