A body covers 10 m in the first 5 s and 20 m in the next 5 s. Find its average speed.

Solve the following examples : An object moves 18 m in the first 3 s, 22 m in the next 3 s and 14 m in the last 3 s. What is the average speed.

Solve the following examples : A person swims 100 m in the first 40 s, 80 m in the next 40 s and 45 m in the last 20 s. What is the average speed ?

Solve the following examples: (numerical problems) A person swims 100 m in the first 40 s, 80 m in the next 40 s and 45 m in the last 20 s. What is the average speed?

Solve the following examples: (numerical problems) An object moves 18 m in the first 3 seconds, 22 m in the next 3 seconds and 14 m in the last 3 seconds. What is its average speed?

A particle travels 10 m in first 5 s and 10 m next 3 s. Assuming constant acceleration what is the distance travelled in next 2 seconds?

A body moves with a velocity of 10 m/s for 10 s and then with a velocity of 20 m/s in the same direction for 40 s. Find its average velocity.

A body moves from A to B at a speed of 10 m/s and back to A along the same path at a speed of 20 m/s. Find its average speed and average velocity for the journey. [Hint : If s is the distance covered by the body between A and B, average speed = (2s)/(t_1 + t_2) = (2s)/[(s/v_1)+(s/v_2)} = (2v_1v_2)/(v_1 + v_2)

A paricle is describing the circular path of radius 20 m in every 2 s. The average angular speed of the particle during 4 s is

A body covers one-half of its journey at 40 m s^-1 and the next half at 50 m s^-1 . Its average velocity is

A body covers one-half of its journey at 40 m s^-1 and the next half at 50 m s^-1 . Its average velocity is.
