Question

a particle starts moving with an acceleration of 4m/s2 . Distance travelled by ut un 3rd sec is?​

Answer 1

Answer:

A particle starts moving with acceleration of 4 meter / sec ² .

Distance travelled by it in 3rd second = ?

Formula used :

Sn = u + 1/2 a ( 2n - 1 )

S3 nd = 10 m

______________________

So, the total distance travelled in 3 seconds = 10 meter .

Deriving the formula Equation :

Sn = u + [ 1/2 a(n)²-1/2a(n-1)²]

Sn = u+1/2a (2n-1)
