Explanation:
By Hooke's Law, Fe = kx.
Since Fe = 1.6N and x = 9.2cm - 8cm = 1.2cm,
k = Fe/x = 1.6N/1.2cm = 1.33N/cm.
It is given that,
Diameter of the semicircle, d = 45 m
Radius of the semicircle, r = 22.5 m
Speed of greyhound, v = 15 m/s
The greyhound is moving under the action of centripetal acceleration. Its formula is given by :
We know that,
Hence, this is the required solution.

Explanation:I studied .
Answer:
c because it makes since
I took the test
Answer:1.96m
Work=4850J
Force=2470N
Distance =work ➗ force
Distance =4850 ➗ 2470
Distance =1.96m
