Question

If a car attains a speed of 36 km/h after acceleration uniformly from rest in 5 second. Find the distance travelled

Answer 1

Answer:

25 m

Explanation:

v= 36 km / hr

=10m/s

t=5

a=v/t

=10/5

=2 m/ s^2

u=0

s=ut+ 1/2at^2

s=1/2* 2* 25

= 25 m

hope it helps.......

Answer 2

Answer:-

S = 25m

Explanation:-

Given:-

• u = 0
• v = 36km/h = 10m/s
• t = 5sec

To Find:

Distance travelled

Solution:-

V = u + at

$V = at$

$10 = a(5)$

$5 = 2 m{s}^{-1}$

Now,

${V}^{2}-{u}^{2}= 2as$

${V}^{2}= 2as$

${10}^{2}= 2(2)s$

$100 = 4s$

$\bold{s = 25m}$
