# Solution: A long jumper leaves the ground at 45 above the horizontal and lands 9.1 v0 away. What is her "takeoff" speed v_0?Will she land on the opposite bank?Now she is out on a hike and comes to the left bank of a river. There is no bridge and the right bank is 10.0 m away horizontally and 2.5 m, vertically below. If she long jumps from the edge of the left bank at 45 with the speed calculated in A, how long, or short, of the opposite bank will she land?

###### Problem

A long jumper leaves the ground at 45 above the horizontal and lands 9.1 v0 away. What is her "takeoff" speed ?

Will she land on the opposite bank?

Now she is out on a hike and comes to the left bank of a river. There is no bridge and the right bank is 10.0 m away horizontally and 2.5 m, vertically below. If she long jumps from the edge of the left bank at 45 with the speed calculated in A, how long, or short, of the opposite bank will she land?
