the net torque about the point (-1 m, 1 m) is 4 N-m.
The resultant force acting on the object is calculated as
R^2=(-5+3)^2+2^2=2.82 N
Distance of the point from the resultant force
d^2=(-1)^2+1^2=1.414
The net torque acting on the point (-1 m, 1 m) is
T=2.82×1.41=3.98 N-m
I have read that it is enough energy to power the needs of civilization for an entire year.
Answer:
Explanation the third one for the second question
Answer:
Compared to the first student, the second student did twice as much work as the first student.
Explanation:
The work done by the first student will be equal to the Force exerted by the backpack on the student carrying it multiplied by one mile (Distance). The work done by the second student will be equal to the Force exerted by the backpack on the student carrying it multiplied by two miles (Distance).
