The force applied on the spring to stretch it is 13.2 N.
Hooke's law is a law of elasticity discovered by the English scientist Robert Hooke in 1660 that states that the displacement or size of a deformation is directly proportional to the deforming force or load for relatively small deformations of an object. When the load is removed under these conditions, the object returns to its original shape and size.
According to Hooke's law, F = k*e
where F is the force on the spring
k is force constant
and e is extension
F = (110)*(0.12)
F = 13.2 N

Answer:
4.96 km/hr
Explanation:
Given that,
A person is running west in Moscow at 2.1 km/hr relative to the ground
Another person is jogging east at 4.5 km/hr.
We need to find the velocity of the jogger relative to the ground. Using the concept of relative speed, let V is the required velocity. So,
So, the velocity of the jogger relative to the ground is 4.96 km/hr.
