Question

HELP ASAP PLEASE!!! A rabbit is hopping to the right with a velocity of 4.0m/s when it sees a carrot up ahead. The rabbit speeds up to its maximum velocity of 13m/s with a constant acceleration of 2.0m/s2 rightward. How many seconds does it take the rabbit to speed up from 4.0m/s to 13m/s?

Answer 1

Answer:

Explanation:

initial velocity(u) = 4 m/s

final velocity(v) = 13 m/s

acceleration(a) = 2m/s^2

time(t) = ?

v = u + at

13 = 4 + 2 × t

13 = 4 + 2t

2t =  13 - 4

2t = 9

t = 9/2

t = 4.5s

hope this helps
