Acceleration in 2D Video Lessons

Concept

Problem: A car is initially at rest at (0, 0) meters on an X-Y plane. The car then accelerates for 4 s with a constant 6 m/s2 directed in the +x-axis. The car then accelerates for 5 s with a constant 5 m/s2 directed at 53° above the +x-axis. Find the magnitude and direction of the car’s velocity after the two accelerations (after 8 s → hint: use v = vo + at).
