Question

Hi
For 10 points...........
I will mark as brain list but
Please tell me answer of 2nd sum with Step-by-step explanation ​

Answer 1

Explanation:

Since, u=7m/s t=4 s S= 92m

Now, S= ut + 1/2 at^2

92 = 7×4 + 1/2a(4) ^2

92-28 = 1/2a × 16

64= 1/2a ×16

64/16 =1/2a

4 = 1/2 a

4×2= a

Therefore, a= 8m/s^2
