The problem involves a box being hurled up an inclined plane at a specific angle and initial velocity, with the goal of determining its velocity after a set time period. The context includes considerations of gravitational effects and the incline's angle.
The discussion is ongoing, with participants providing feedback on calculations and clarifying potential errors in the original poster's approach. There is acknowledgment of a correction regarding the values used in the calculations, but no consensus on the final outcome has been reached.
Participants note the absence of friction and the specific angle of the incline, which are crucial to the problem setup. There is also mention of potential confusion in the calculations that may have led to incorrect results.

A box is hurled up an incline plane of 20 degrees at 10m/second. There is no friction. What is the velocity after 3 seconds. I know gravity and the sin of 20 degrees has to be factored in.
Homework Equations
v=u+at. u is initial velocity, v is velocity after 3 seconds, t is time.
The Attempt at a Solution
9.81x.342=3.355ms^-2. Using the above equation I calculate -.065m/s (10-3.55x3). This does not match any of my answers. I do not know were I went off-track.
