Answer:
7040.76 Joule
Step-by-step explanation:
In order to make yourself be able to climb upstairs, you need to work against the force of gravity. The force with which you pull yourself up is equal to the force of gravity exerted on you by the gravitational force.
So here, the net force involved is Mass(in Kg) multiplied by Acceleration due to gravity.
132 pounds = 59.8742 Kg
Net force = 59.87 × 9.8 = 586.73
As we know, the workdone is calculated by Multiplying the Net force with the Net displacement. Here, in this case the net displacement is 12 meters.
So,
Workdone = 586.73 × 12 = 7040.76 Joule
Answer: 4
Step-by-step explanation: Slopes that are perpendicular to each other are opposite reciprocals. So take the opposite of the sign, negative or positive. Then flip the numerator and the denominator. -1/4 goes to +1/4 goes to +4. Hope this helps!
