Explanation:
That can only be happening if the mass mysteriously increased somehow. I'd like to know how in the world THAT happened.
Answer:
Explanation:
Hooke's law is represented by thee formula
F = ke where F is force in N and K is the spring constant.
Initial length of the spring = 34cm = 0.34 m
mass of 7.00kg hung
weight = mg = 7 × 9.8 = 68.6 N
Final length of the spring = 44.5 cm = 0.445 m
extension = final length - initial length = 0.445 m - 0.34 m = 0.105 m
a) F = Ke
K = F / e = 68.6 N /0.105 m = 653.33 N/m = 0.653 kN/m
b) F = 150 N
k = 653.33 N/m
F = ke
150 N / 653.33 N/m = e
e = 0.23 m
new length = 0.34 + 0.23= 0.57 m = 57 cm

Explanation:
thats your answer
Since we are talking about the relation between the velocity and the time, the distance must be given.
Since no distance is given here, then I'll just tell you how to solve this question in terms of equations and you can substitute with the numbers you have.
The velocity can be calculated using the following rule:
velocity = distance / time
we are given the time as 3.5 seconds, therefore:
velocity = distance / 3.5
