(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A particle has an initial horizontal velocity of 2.6 m/s and an initial upward velocity of 3.5 m/s. It is then given a horizontal acceleration of 1.3 m/s^2 and a downward acceleration of 1.2 m/s^2.

What is its speed after 2.2 s?

What is the direction of its velocity at this time with respect to the horizontal (answer between -180º and +180º)

2. Relevant equations

all kinematic equations

3. The attempt at a solution

i'm lost on this one
