Question
A rabbit sees carrot to his right and starts jumping towards it with a velocity of 4.0meter per sec it speeds up to its maximum velocity of 13 meter per sec with a constant acceleration of 2.0 metre per sec square how long does it take for the rabbit to go from 4.0 metre per sec to 13.0 metre per square

Answer:
4.5 s
Explanation:
The initial velocity (u) = 4 m/s, the final velocity (v) = 13 m/s and the acceleration (a) = 2 m/s²
To calculate the time it takes the rabbit to go from 4.0 m/s to 13.0 m/s, we use the formula:
v = u + at
Substituting values to get:
13 = 4 + 2t
Subtracting 4 from both sides:
13 – 4 = 4 + 2t – 4
9 = 2t
Therefore, 2t = 9
Dividing through by 2
2t / 2 = 9 / 2
t = 4.5 s
Therefore it takes the rabbit 4.5 seconds to go from 4.0 m/s to 13.0 m/s
Answer:
4.5 sec
Explanation:
Initial velocity u = 4 m/s
Final velocity v = 13 m/s
Acceleratiin a = 2 m/s^2
Using v = u + at
Where t is time
13 = 4 + 2t
13 – 4 = 2t
9 = 2t
t = 9/2 = 4.5 sec
