Question #243530

A fighter plane travelling horizontally at 1.0x10^2m/s drops a rocket from a height of -1.00x10^3m.

Expert's answer

The vertical component of rocket's velocity as it reaches the ground (assuming it does not have an engine) is

"v_y=\\sqrt{2gh}=\\sqrt{2\u00b79.8\u00b71000}=140\\text{ m\/s}."
