Question

Given that v = 5 + 6t, at what time the final velocity will be 41m/s?​

Answer 1

Answer:

v=5+8t

(t=5secs)

v=5+8×5

v=5+40

v=45m/s

Answer 2

Answer:

v = 5 + 6t

We have, final velocity v = 41m/s

41 = 5 + 6t

After solving we get the value of t = 6s.

We can further verify our answer by putting the value of t = 6 in v = 5+6t

That'll give us v = 41m/s which is correct.
