FIGURE Q2.11

When there is air resistance present how to the velocity and acceleration vectors behave?   a.The acceleration and velocity vectors are both constant magnitude but continually change direction.   b.The acceleration vector is constant and points straight down. The velocity vector is at a tangent to the trajectory   c.The acceleration vector is perpendicular to the trajectory and the velocity vector is at a tangent to it.   d.The acceleration changes throughout the flight with its x-component opposite the direction of motion. The velocity vector is at a tangent to the trajectory

Steph Curry launches a basketball from a height of 2.36 m above the ground from the free throw line, which is 4.191 m to the left of the center of the hoop. The basketball makes it through the hoop, which is 3.048 meters above the ground, 1.13 seconds later. a.) what is the basketball's velocity when it leaves Steph's hands? b.) what is the basketball's velocity as it passes through the hoop?

6. A car starts from rest and accelerates at a rate of 1.8 m/s² West for 15s. It goes at a constant velocity for 50s and then accelerates at a rate of 2.1m/s² East for 10 s. Use West as the positive direction. a. Draw an acceleration graph for this situation. Remember to quantitatively label your axes. a (m/812) t(s) 0-15 15-65 65-75 b. What is the change in velocity for each time interval? Av (m/s) t(s) Draw a velocity graph for this situation. Remember to quantitatively label your axes. v (m/s) E t(s) d. What is the total displacement between t-Os and t= 75 s?
