?

Answer 1

a = v^2/r

Answer 2

84^2/225

Answer 3

31.36

Answer 4

good

units of acceleration are m/s/s

Answer 5

for b just divide the acceleration by g (9.8)

Answer 6

3.2

Answer 7

good, so 3.2 g

for c) solve for v using 9.8 as a and the original radius as r

Answer 8

2205

Answer 9

a = v^2/r

9.8 = v^2/225

v = ?

Answer 10

47

Answer 11

good

Answer 12

speed so would it be m/s

Answer 13

yes
