Question

a body moves from rest with a uniform accleratiin and travels 450 m in 9s . find the velocity of the body at 10s after the start​

Answer 1

Answer:

a body moves from rest with a uniform accleratiin and travels 450 m in 9s . find the velocity of the body at 10s after the start

600 meter square

Answer 2

Answer:

Given :

A body moves with a uniform acceleration

Initial v = om/s

and distance travel = 450m

Time = 9s

First we solve acceleration the we

solve in second case i.e final velocity

Now let's solve

S = ut+1/2at^2

S = 0×9 +1/2×a×9^2

450 ×2 = 81a

a = 900/81

a = 11.11 m/s^2

Therefore = a = 11.11m/s^2.

Now in second case

Initial velocity= 0m/s

Final(v) = ?

Time = 10S

a = 11.11m/s^2

V = u+at

V = 0+11.11×10

v = 111.1 m/s

Hence final velocity= 111.1m/s
