Quiz 1: Vectors and One-Dimensional Motion Question 1: The OU-OSU football game is tied and only enough time remains on the clock for one last field goal attempt for the Cowboys. The ball will be kicked from the 45-yard (41m) line. The cross bar of the goal post is 10ft (3.0m) high and lies 10 yards (9.1m) behind the goal line. If the ball leaves the kicker's foot at an angle of 40 to the ground, what initial velocity is required in order for OSU to win the ball game? a. Find initial velocity required for OSU to win the game. b. Find the time the football is in the air from when it's kicked to when it hits the ground. c. Find the final velocity it hits the ground at. d. Find horizontal acceleration of ball after it is kicked Question 2: A person stands at the edge of a cliff and throws a pebble horizontally over the edge with a speed of v0 = 16.0 m/s. The pebble leaves his hand at a height of h = 37.0 m above level ground at the bottom of the cliff, as shown in the figure. Note the coordinate system in the figure, where the origin is at the bottom of the cliff, directly below where the pebble leaves the hand. a. What are the coordinates of the initial position of the pebble (x = m__ and y = m _? b. What are the components of the initial velocity (V x and Vy)? c. How long (in s) after being released does the pebble strike the ground below the cliff? d. With what speed (in m/s) and angle of impact (in degrees clockwise from the +x- axis) does the pebble land
