Question

pls answer I will definitely make brainlist but I need step by step explanation plss​

Answer 1

Answer:

Acceleration = 6m/s²

Initial Velocity = 21m/s

Time = 8s

First let's find Final Velocity

v = u + at

v = 21 + 6(8)

v = 21 + 48

v = 69 m/s

Now distance will be

2as = v² - u²

2(6)(s) = (69)² - (21)²

12 s = 4761 - 441

s = 4320/12

s = 360 m

Hope it helps!
