Answer 1

The answer is "
`0.13562748`"

Step-by-step explanation:

Please find the complete question in the attached file.

Using formula:

`\bold{U_s=(v^2)/(rg)}`

Given:

`r=1.60 * 10^2 \ m\\\\g=9.8\\\\v= 52.5\ (km)/(hr)= 14.583\ (m)/(s)`

put the value into the above-given formula:

`U_s= (14.583^2)/(160 * 9.8)`

`= (212.663889)/(1568)\\\\=0.13562748`
