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:
The work done by the torque is the same in each case.
Explanation:
Work-Energy Theorem can be used to calculate the work done by the torque in each case.
Let's apply this theorem to each case:
As can be seen from the results, in each case the work done by the torque is the same.
Answer:
The acceleration of the box is 3 m/s²
Explanation:
Given;
mass of the box, m = 12 kg
horizontal force pulling the box forward, Fx = 48 N
frictional force acting against the box in opposite direction, Fk = 12 N
The net horizontal force on the box, F = 48 N - 12 N
The net horizontal force on the box, F = 36 N
Apply Newton's second law of motion to determine the acceleration of the box;
F = ma
where;
F is the net horizontal force on the box
a is the acceleration of the box
a = F / m
a = 36 / 12
a = 3 m/s²
Therefore, the acceleration of the box is 3 m/s²
