2) Max must prove his love to Jenna, who he’s asked tomarry him. She assures him she will, if he walks to the top of Mount Minnetonka and brings her one drop of the water from the lake that Prince made famous in his 1984 movie, Purple Rain.

b.We must assume vf= 0 m/s
c.We must assume v0= 0 m/s
d.We must solve for d
