31-36 Write on This Question Sheet! Use g = 9.8 m/s^2. The magnitude of the acceleration due to gravity on Earth is: 6.3 m/s^2 9.8 m/s^2 11.3m/s^2 12.6m/s^2 22.6m/s2 An experiment to determine the acceleration due to gravity is held on a planet other than Earth. It yields a speed vs. time function of v(t) - 12.6 t + 22.6 (in SI Units). What is the magnitude of the acceleration due to gravity on this other planet? 9.8 m/s^2 11.3m/s^2 12.6m/s^2 22.6m/s^2 25.2m/s^2 An experiment measures the position vs. time of on object. At t = 4.0 s, the slope of the graph is 0.5 and at t - 6.0 s, the slope of the graph is also 0.5. What is the acceleration of the object? 0.125 m/s^2 0.25 m/s^2 0.5 m/s^2 1.0 m/s^2 0.0 m/s^2 An experiment measures the velocity vs. time of an object. At t = 4.0. the slope of the graph is 0.5 and at t = 6.0, the slope of the graph is also 0.5. What is the acceleration of the object? 0.125 m/s^2 0.25 m/s^2 0.5 m/s^2 1.0 m/s^2 0.0 m/s^2 For an object dropped from rest, the distance fallen follows the relationship h = 1/2gt^2. What is the proper algebraic manipulation to solve for t? t = 1/2gh^2 t = 1/2 h squareroot h t = (2 squareroot h)/g t = squareroot h/(2g) e. t = squareroot 2h/g A ball is fired horizontally from a launcher that is 1.32 m above the floor. The range of the shot is 2.35 m. The speed of firing is closest to 0.5 m/s 0.7 m/s 2.5 m/s 4.5 m/s 7.4 m/s

Explanation / Answer

(31) b

(32) Acceleration is the derivative of time with respect to t. Hence the answer is c.

(33) The slope of the position vs time plot gives the velocity of the particle. The velocity of the particle is observed to be the same from the given data. Therefore acceleration is 0.

(34)  The slope of the velocity vs time plot gives the acceleration of the particle. The acceleration of the particle is observed to be the same from the given data. Therefore the acceleration is 0.5 m/s^2

(35) e
