acceleration and travels 270 m in 3 s. Find the
velocity of the body at 10 s after the start.
Ans. 600 m s-1
Answers
Answer:
Explanation:
From the first condition, applying the equation:
;where s = displacement
u = initial velocity
a = acceleration
t = time.
We get =>
=>
Now, we have time and acceleration and have to find velocity.
Therefore, applying : ; where v = final velocity
u = initial velocity
a = acceleration
t = time.
We get =>
=>
