Answer:

When the glider dives, its speed increases due to the acceleration of gravity on the glider.

Using the kinematics equation:

Vf^2 = Vi^2 + 2g delta y you can determine the final speed

Vi = 45.2 m/s

Vf is unknown

delta y = 416- 278 = 138 m

g = 9.8 m/s/s

Vf^2 = 45.2^2 + 2 *9.8 * 138

solve for Vf

Vf = 68.9 m/s
