Question

a body starting from rest covers a distance of 0.45km and acquired a velocity of 300km/hr its acceleration will be

Answer 1

Answer:

200000 m/s^2

Explanation:

Here,

u = 0km/hr

v = 300km/hr

and s = 0.45km/hr

Time= 0.45/300. (distance/speed)

=45/30000

=0.0015 secs

Now,

v = u+at

300 = 0.0015 ×a

300 = 0.0015a

a = 300/0.0015

= 3000000/15

That is equal to the answer that is

200000 m/s^2
