The correct answer among the choices given is the last option. In Florida, the standard defined speed limit in a residential area is 30 mph. In the United States, the speed limit in urban areas is 30 mph and in unpaved roads is 35 mph. In interstate roads the limit is at 70 mph.
Answer:
A. 1.8x10⁵
Explanation:
For this question we have
72km/h = speed
Total mass = 2250kg
Stopped at t = 0.2250s
To get average force acting on this car on collision:
72km/3.6 = 20m|s
Impulse = ∆p
This implies:
F∆t = m∆v
F = m∆v/∆t
= 2250x20/0.250
= 180000
= 1.8x10⁵
Therefore option A is correct.
I’m pretty sure the answer is A
Zeroth Law of Thermodynamics, which in turn will mean the heat will transfer between both of them up to the point where they are in thermodynamic equilibrium. So the answer is C.
