A particle initially at the origin is moving initially at 4.10 m/s at an angle of 33.5 o above the horizontal. Two seconds later, its velocity is 6.05 m/s at an angle of 59.0o below the horizontal. Assume the particle to have constant acceleration. a. What was the magnitude of the particle's acceleration during these 2.00 s? b.What was the direction of the particle's acceleration during these 2.00 s? c. What was the magnitude of the particle's displacement during these 2.00 s? d. What was the direction of the particle's displacement during these 2.00 s? e. What is the magnitude and direction of the particle's average velocity during these 2.00 s? Please show steps to how you got your answers, as this question really stumped me and I can't seem to understand the sudden change in direction and velocity.
