Question

Initially a body at rest. If its acceleration is 6m/s2 then the distance travelled in the 18th second is

Answer 1

Hi.

________________

Initial Velocity (u) = 0
[Since the body is at rest]
Time = 18 seconds.
Acceleration = 6 m/s²

Using the Formula,
  
    $Acceleration = \frac{v - u}{t}$
                             6 = (v - 0)/18
                              v = 6 × 18
                              v = 108 m/s

Thus, the velocity of the object is 108 m/s.


Hope it helps

Answer 2

(u) = 0

t= 18 seconds.

a = 6 m/s²

a=v - u/t

6 = (v - 0)/18

v = 6 × 18

v = 108 m/s
