Question

U=10m/s,V=0,A= 100m/s² find distance

Answer 1

Answer:

Given :

u = 10m/s

v = 0m/s

a = 100m/s^2

➪ 1st , we have to find time :

formula : t = v - u / a

☞︎︎︎ solution :

t = 0 - 10m/s /100m/s^2

t = -0.1 s

➪ 2nd , to find distance ,

We have ,

u = 10m/s

a = 100m/s^2

t = 0.1s

d = ?

formula : s = ut + 1/2at^2

☞︎︎︎ solution :

s = 10m/s * 0.1s + 1/2 * 100m/s^2 * ( 0.1s)^2

s = 1m + 500m/s^2 * 0.01s^2

s = 1m + 500m/s^2 * 1/100s^2

s = 1m + 5m

s = 6m

hence , the distance will be 6 m .

Answer 2

Answer:

1st , we have to find time ,

_____________✨

t = v - u / a

= 0 - 10m/s/ -100m/s^2

= 0.1s

then , the distance be ,

_____________❄️

s = ut + 1/2at^2

= 10m/s * 0.1s + 1/2*-100m/s^2 *( 0.1s)^2

= 1m + 5m

= 6m
