Question

The velocity time graph of aball is given below.
What is the acceleration of the balll
1) during 10s?
2) between 10s and 35s?
3) during 35s to 40s?

Answer 1

explanation

1)).

v=10m/s ,u= 0m/s, t= 10s

then,

a= v-u/t.

= 10-0/10

= 10/10m/s²

= 1m/s²

2). v =10m/s, u= 10m/s, t = 25s

then,

a=v-u/t

= 10-10/25

= 0/25

= Om/s²

3).v= 10m/s, u =0m/s, t= 5s

then,

a= v-u/t

= 10-0/5

= 2m/s²
