Answer
To find the change in velocity, we can use the acceleration formula:
extChangeinvelocity=at
where:
(a = 2 \text{ m/s}^2)
(t = 4 \text{ s})
So,
extChangeinvelocity=2×4=8 m/s
Step 2
Calculate the final velocity (v)

Answer
Using the formula:
v=u+at
where:
(u = 3 \text{ m/s})
Change in velocity = 8 m/s
We can now substitute the values:
v=3+8=11 m/s
Therefore, the final velocity of the leopard is 11 m/s.
