Step 1

Given:

Initial velocity of the object = 0 m/s

Acceleration of an object falling freely = g = 9.8 m/s2

Step 2

Substitute u
0 m/s, t 10 s, a= g = 9.8 m/s2
S 0+(9.810) = 490m ....(1)
Total time taken, t = 10 s (Given)
Average speed is defined as the ratio of total distance travelled by per unit time.
s 490m49m/s
So, Average speed=
