Mr.Becks gigantic gas- guzzling exhaust spewing urban assault vehicle suburban weighs 10000 pounds it takes Mr Beck 2 minutes to drive 1.5 kilometers to west valley fitness so he can ride the stationary exercise bike for a half hour How much work and power did the suburban do?
A.work
B.power
To calculate the work done by the suburban, we need to use the formula:
Work = Force × Distance
Since the question does not provide any specific force acting on the suburban, we can assume that the force is equal to the weight of the suburban. The weight is given as 10000 pounds.
Now, we need to calculate the distance in SI units (meters) instead of kilometers. 1 kilometer is equal to 1000 meters. So, 1.5 kilometers is equal to 1.5 × 1000 = 1500 meters.
Therefore, the work done by the suburban can be calculated as:
Work = 10000 pounds × 1500 meters
However, we need to convert the weight from pounds to Newtons (SI unit of force). 1 pound is equal to approximately 4.448 Newtons.
So, the weight of the suburban in Newtons is:
Weight = 10000 pounds × 4.448 Newtons/pound
Now, we can calculate the work done using the weight in Newtons:
Work = Weight × Distance
To calculate the power, we need to use the formula:
Power = Work ÷ Time
The time given is 2 minutes, but we need to convert it to seconds. 1 minute is equal to 60 seconds. So, 2 minutes is equal to 2 × 60 = 120 seconds.
Substituting the values into the formula, we can calculate the power.
