Answer this :

Q. Rahul white doing skating moves along a number line in the alphabetical order (A, B, C, D, ....., G) and finally stops at 'G'.

(a) Calculate the distance travelled by him.

(b) Find the average velocity if he covers each meter in 1 s.

(b) Find the average velocity if he covers each meter in 1 s.

from b to c - 5 m

from c to d - 4 m

from d to e - 3 m

from e to f - 2 m

from f to g - 1 m

total distance travelled =6+5+4+3+2+1=21 m

ii) average velocity = displacement / time

from a to g - 3 m..i.e displacement = 3 m

therefore average velocity = 3 m s
