Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. 001 10.0 points When the Sun is directly overhead, a hawk dives toward the ground at a speed oF 5 . 72 m / s. IF the direction oF his motion is at an angle oF 50 . 1 below the horizontal, calculate the speed oF his shadow moving along the ground. Answer in units oF m / s. 002 10.0 points A quarterback takes the ball From the line oF scrimmage, runs backward For 17 yards, then runs sideways parallel to the line oF scrim- mage For 20 yards. At this point, he throws a 22 yards Forward pass straight downfeld perpendicular to the line oF scrimmage. What is the magnitude oF the Football’s resultant displacement? Answer in units oF yards. 003 (part 1 oF 2) 10.0 points Consider three Force vectors v F 1 , v F 2 , and v F 3 . The vector v F 1 has magnitude

Unformatted text preview: F 1 = 49 N and direction 1 = 71 ; the vector v F 2 has mag-nitude F 2 = 29 N and direction 2 =-20 ; and the vector v F 3 has magnitude F 3 = 17 N and direction 3 = 130 . All the direction an-gles are measured From the positive x axis: counter-clockwise For > 0 and clockwise For < 0. What is the magnitude F oF the net Force vector v F = v F 1 + v F 2 + v F 3 ? Answer in units oF N. 004 (part 2 oF 2) 10.0 points What is the direction oF the net Force vector v F ? State your answer as an angle between-180 and +180 . Answer in units oF . 005 (part 1 oF 2) 10.0 points Vector v B has x , y , and z components oF 6 . 6, 5 . 2, and 4 . 2 units, respectively. Calculate the magnitude oF v B . 006 (part 2 oF 2) 10.0 points What is the angle between v B and the x-axis? Answer in units oF ....
