1 The magnitude of a vector... a Must always include direction c Can never be less than one of its components b Can be less than one of its components d must include unit vectors 2 Given the vector ?A = 4.00î + 7.00?, find the magnitude of the vector. a 5.74 c 8.06 b 3.31 d 65.00 3 Based on the graph shown for a moving particle at the right what is the instantaneous acceleration of the object at 25.0s? a 25.0 m/s^2 c 0.5 m/s^2 b 9.8 m/s^2 d 0.0 m/s^2 4 The graph to the right shows the position of two cars over time. At which point do the cars pass one another? a A c C b B d D e E 5 A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 100. m above ground level, and the ball is fired with initial horizontal speed v0. Assume acceleration due to gravity to be g = 9.80 m/s^2. How long does it take the cannonball to hit the ground? a 4.52s c 3.19s b 20.41s d 14.14s 6 Which of the following is not an Acceleration? a Someone falling off a leaning tower c A leaning tower coming loose and crashing to the ground b A bunch of ruble and other things being d A stationary person on a stationary thrown in random directions spaceship watching a tower fall over from a cool telescope.
