Question

a car starts from rest attains a speed of 36 km/hr in 5 sec find its acceleration​

Answer 1

Answer

time =x.

36 km /hr into m/s v=10m/s u= 0

36×5/18=10m/s

10/x=1/5 used formula=(v-u)/t

x=50 sec

for distance =

v^2-u2=2as where a = acc. and s = distance

100=2×1/5×s

s=250m

Hope this helps you

Answer 2

Hi..

Here's ur answer

u = 0

v = 36km/hr = 36×5/18 m/s = 10m/s

t = 5 s

a = ?

a = (v-u) /t

a = (10 - 0) / 5

a = 10/5

a = 2 m/s²

Hope it helps u
