Final answer:
George the bunny took approximately 6.667 seconds to speed up from 15 m/s to 35 m/s.
Step-by-step explanation:
To find the time it took for George the bunny to speed up, we can use the equation:
Δv = a × t
Where Δv is the change in velocity, a is the acceleration, and t is the time. In this case, the initial velocity u is 15 m/s, the final velocity v is 35 m/s, and the acceleration a is 3 m/s2. Plugging in the values, we get:
35 - 15 = 3 × t
Simplifying the equation, we have:
20 = 3t
Dividing both sides by 3, we find:
t = 20/3 = 6.667 seconds
Therefore, it took George approximately 6.667 seconds to speed up.
