A car turns a corner that has a radius of 5 m and experiences a centripetal acceleration of 20 m/s. If the radius of turn were increased to 10 m, what is the centripetal acceleration?

It becomes 10 #ms^2#

Explanation:

The centripetal acceleration halves, because
if you look at the centripetal acceleration formula, you'll see why.
#a# #=# #v^2/r#
#a# is inversely proportional to #r#

For example
#a# #=# #10^2/5#

#a# #=# #20#

#a# #=# #10^2/10#

#a# #=# #10#

#a# halves
