Answer:
The further the spring is stretched from its origin.
Explanation:
When a spring is stretched or compressed from its original source, a restoring force will act, trying to bring it back to its original state. Hence, Hooke's Law states that the extension of an elastic material is proportional to the load applied or force applied to it. This will continue to hold provided the elastic limit of such material is not exceeded. Therefore, the more it is pull away from the original state, the more restoring force act on it and the more force the that will be needed to pull it away provided the elastic limit is not exceeded.
Answer:
0.54m
Explanation:
Step one:
given data
length of seesaw= 3m
mass of man m1= 85kg
weight = mg
W1= 85*10= 850N
mass of daughter m2= 35kg
W2= 35*10= 350N
distance from the center= (1.5-0.2)= 1.3m
Step two:
we know that the sum of clockwise moment equals the anticlockwise moment
let the distance the must sit to balance the system be x
taking moment about the center of the system
350*1.3=850*x
455=850x
divide both sides by 850
x=455/850
x=0.54
Hence the man must sit 0.54m from the right to balance the system
According to Newton's first law of motion, if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed. Galileo realized the motion of an object doesn't change until an unbalanced force acts on it.
