Saara zamana...

Physics ka deewana.. xD

Do solve this question in attachment..
​

Answer 1

u=0 cm/s

Sn=120 cm/s

n=6

let a be the acceleration

To solve this problem you should know the formula

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

where Sn=distance travelled in nth second

plugging the values

120=0+a*(6*2-1)/2

120=a*11/2

a=21.818 cm/s²

Hope this helps

Answer 2

Answer:

acceleration = (v-u)/t = 120-0/6 = 20cm/s answer.
