Homework Statement

Having captured a mouse, an owl is flying towards the barn where it lives to enjoy dinner. While approaching the barn at a speed of 6.5 m/s at an upwards angle of 11o above the horizontal, the struggling mouse escapes from the talons of the owl while at an altitude of 6.3 m. How much times passes before the mouse hits the ground?

Homework Equations

y=ynot+ vnot Δt +1/2aΔt

The Attempt at a Solution

i used my vnot 6.5m/s and v 6.5sin11. then did the quadratic equation to find Δt but i keep getting the wrong answer.

The velocity is at an angle. The time to the ground depends on its vertical component, not its entire magnitude.
