Th equations to be used here are the following:
a = (v - v₀)/t
x = v₀t + 0.5at²
The speed of the fugitive is the sum of his own speed plus the speed of the train. Thus,
v₀ = 0 + 5.5 m/s = 5.5 m/s
v = 8 m/s + 5.5 m/s = 13.5 m/s
a.) We use the first equation to determine time
2.5 m/s² = (13.5 m/s - 5.5 m/s)t
Solving for t,
t = 3.2 seconds
b.) We use the answer in a) and the 2nd equation:
x = (5.5 m/s)(3.2 s) + 0.5(2.5 m/s²)(3.2 s)²
x = 30.4 meters
Answer: The student with the largest measurement of percentage error is student 4. Option A is correct.The percent error shows the disparity between the observed value and the actual value. It is given by the expression.
Therefore, we can conclude that the student's measurement that has the largest percent error is student 4.

Answer:
When the system is in thermal equilibrium
Explanation:
You know the transfer of thermal energy has ended when the temperature is uniform in the system.
Answer:
8 hp
Explanation:
Power = work / time
P = W/t
Work = force × distance
W = Fd
Substituting:
P = Fd/t
P = Fv
Given that F = 300 N and v = 20 m/s:
P = (300 N) (20 m/s)
P = 6000 W
P = 6 kW
Converting to horse power:
6 kW × (1 hp / ¾ kW) = 8 hp
