17- a- What is the acceleration of the ball during the first 5 s (rising)? What is its acceleration during the last 5 s of the motion (falling)? b- What is the velocity of the ball at t = 5 s? c- If the initial velocity of the ball at t=0 s is 3.5 m/s, what is its final velocity at t- 10s (without calculation)? d- If the velocity of the ball at t-2 s is 3 m/s, what is its velocity at t = 8 s? 18-The x and y components of a vector r are rx = 14 m and ry= -9.5 m, respectively. a. Find the magnitude of the vector r b. Find the direction of vector r c. If both r, and ry are doubled, how do your answers to parts (a) and (b) change? A Vertical Position ( 2
