Answer:
a) The maximum possible acceleration the truck can give the SUV is 7.5 meters per second squared
b) The force of the SUV's bumper on the truck's bumper is 18000 newtons
Explanation:
a) By Newton's second law we can find the relation between force and acceleration of the SUV:
With F the maximum force the truck applies to the SUV, m the mass of the SUV and a the acceleration of the SUV; solving for a:
b) Because at this acceleration the truck's bumper makes a force of 18000 N on the SUV’s bumper by Third Newton’s law the force of the SUV’s bumper on the truck’s bumper is 18000 N too because they are action-reaction force pairs.
Answer:
-20v
Explanation:
Data provided in the question as per the given situation
L = 45 mH
f = 250 Hz
V_o = 20V
Based on the above information, let us assume voltage across inductor be V at t
So,
t = 2 ms
Now
The voltage at time t = 2.0 ms is
= -20 volt
= -20v
We simply solved the above equation so that the correct voltage could come
~Formula: Voltage= current• resistance
(V= Ir)
~Using this formula, plug in the numbers from the equation into the formula
~5=25i
~Now you have a one-step equation
~Divide by 25 on both sides and you should get your answer:
~I= 0.2 (which means current is 0.2)
If the US
government does not allow the manufacturer to export their products to
Honduras, the manufacturer will lose
the non-refundable application fee of $2,700 and because the U.S. government
limits trade with Honduras, the manufacturer is required to obtain an export
license from the Department of Commerce, which can result to a shortage of
demand for US products.
In addition, the total value of product exports must
not less than $10800 for the duration of the license so that the application
and license fee will be worthwhile.
