a plane drops a hamper of medical supplies from a height of 3160 m during a practice run over the ocean.?

The plane’s horizontal velocity was 125 m/s at the instant the hamper was dropped. The acceleration of gravity is 9.8 m/s/s. What is the magnitude of the overall velocity of the hamper at the instant it strikes the surface of the ocean? answer in units of m/s

Ignoring air resistance the hamper will continue to have horizontal speed of 125 m/s. It will gain vertical speed of
-9.81*t
where t is related to the height as
0=3160-.5*9.81*t^2
t=25.4
the vertical speed is -249 m/s

The magnitude of the velocity is
=sqrt(vx^2+vy^2)
278 m/s
