Answer:
W = 55.12 J
Explanation:
Given,
Natural length = 6 in
Force = 4 lb, stretched length = 8.4 in
We know,
F = k x
k is spring constant
4 = k (8.4-6)
k = 1.67 lb/in
Work done to stretch the spring to 10.1 in.
![W = \dfrac{k}{2}[x^2]_6^{10.1}](https://tex.z-dn.net/?f=W%20%3D%20%5Cdfrac%7Bk%7D%7B2%7D%5Bx%5E2%5D_6%5E%7B10.1%7D)
W = 55.12 J
Work done in stretching spring from 6 in to 10.1 in is equal to 55.12 J.

Answer:
Acceleration will 7.5 times g = 7.5 g
Explanation:
Centripetal acceleration is given by a = v²/r.
The speed in m/s will be; (96.6 Km/h )÷ 3.6
= 26.83 m/s.
Centripetal force = v²/r
= 26.83²/9.80
= 73.454 m/s²
But; g = 9.8 m/s²
Therefore the acceleration in terms of g will be;
= 73.454/9.8
= 7.5 g
Acceleration is 7.5 g
