Answer:
The correct answer would be B) Scalar
Hi, we can do a comparisson. Recall that potential energy is defined as m*g*h where m is the mass in kg, g is gravitational acceleration (9.8m/s^2) and h is the height therefore:
A:B:C:D=30×g×1.5:20×g×2:30×g×2:20×g×1.5 since all of them have the term of g, we can "kill" the term hence we have that:
A:B:C:D=45:40:60:30 hence we know the option c has the most potential energy
Answer:
P = 34034.2 Watt
Explanation:
As we know that the slope angle is given as
now the weight of the rider along the slope is given as
now total weight of all 53 riders along the slope is given as
now the speed of the rope is given as
now the power required is given as
