Given:
Initial speed = 30 m/s
Acceleration = 3 m/s^2
Time = 5 seconds
Determine the Final Velocity.
Formula for Acceleration:
a = (vf - vi)/t
a = acceleration
vf = final velocity
vi = initial velocity
t = time
vf = at + vi
Solution:
Substitute the given values of vi, a, and t to the formula for vf.
vf = at + vi
vf = (3 m/s^2)(5s) + 30 m/s
vf = 15 m/s + 30 m/s
vf = 45 m/s
Final answer:
The final velocity of the lion is 45 ms.
