3. Average Speed- Case I
? If a particle travels distances x1,x2,x3..... with speeds v1 , v2
v3..... in some direction then,
Total distance travelled =
Total time taken=
5. A body covers one half of its journey at
40 m/s and the next half at 50 m/s.
Find its average velocity.
6. Average Speed- Case II
? If a particle travels. with speeds v1 , v2 ,v3..... In time
intervals t1 , t2 ,t3..... Respectively in some direction
then,
Total distance travelled =
Total time taken=
10. A ball falls freely from rest. Find the ratio
of the distances travelled in 1st, 2nd, 3rd, and
4th second.
Prove that the ratio of distances travelled by a
freely falling body is the ratio of odd numbers.
