Question

ANSWER ONLY WITH COMPLETE EXPLAINATION FROM BASICS. SUCH WILL GET BRAINLIEST IMMEDIATELY!!​

Answer 1

Explanation:

As we know that , for nth second

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

Given, s = 2+3n

=> 2+3n = u + a(2n-1)/2

=> 2+3n = u + an - a/2

Now comparing both side , we get

u - a/2 = 2. &. an = 3n

=> u = 2 + a/2. &. a = 3

=> u = 3.5m/s^2

•°• u = 3.5m/s^ and a = 3m/s^2

→ at t = 2sec

s = 2+3×2 = 8m

•°• velocity = 8/2 = 4m/s

Hope it help
