Initially, a particle is moving at 4.50 m/s at an angle of 35.0° above the horizontal (+x axis). Two seconds later, its velocity is 5.79 m/s at an angle of 50.0° below the horizontal. What was the particle's average acceleration during these 2.00 seconds?
1. m/s2 (x component)
2. m/s2 (y component)
V1 = 4.5 cos35i + 4.5 sin35j = 3.69i + 2.58j
V2 = 5.79 cos50i - 5.79 sin50j = 3.72i - 4.44j
Average acceleration, a = (V2 - V1) /t
ax = 0.015 m/s^2
ay = - 3.51 m/s^2

A racquetball of mass m = 42.9 g, initially moving at 35.0 m/s horizontally in the positive x direction, is struck by a racket. After being struck, the ball moves back in the opposite direction at an angle of 35.0° above the horizontal with a speed of 62.0 m/s. What is the average vector force exerted on the racket by the ball if they are in contact for 2.60 ms? (Assume the positive y direction is vertically upward. Express your...
