If a pronghorn antelope accelerates from rest in a straight line with a constant acceleration of 1.4m/s^2, how long does it take for the antelope to reach a speed of 23m/s?
____s
I will be happy to critique your thinking.
To find the time it takes for the antelope to reach a speed of 23m/s, you can use the equation of motion:
v = u + at
Where:
v = final velocity (23 m/s)
u = initial velocity (0 m/s, as the antelope starts from rest)
a = acceleration (1.4 m/s^2)
t = time
Rearranging the equation to solve for time:
t = (v - u) / a
Plugging in the given values:
t = (23 m/s - 0 m/s) / 1.4 m/s^2
Simplifying:
t = 23 m/s / 1.4 m/s^2
t ≈ 16.43 seconds
Therefore, it takes approximately 16.43 seconds for the pronghorn antelope to reach a speed of 23m/s.
