Physics 12 –Vector Refresher1)Label each quantity as either a scalar (S) or a vector (V). _____ Distance _____ Displacement _____ Velocity _____ Force _____ Time _____ Acceleration _____ Speed _____ Area _____ Mass 2)Find the x and y components of the Jet’s initial velocity(answers on last page) 3)If the x and y components of the plane velocity are shown. Determine how fast the plane was going and at what angle. 4)For each vector described below, draw a coordinate system (x and y axis) and sketch the vector. Be sure to indicate where the angle is and label the vector on your diagram. a) A man walks 800m in a direction of 20.0oWest of North. b)A worker lifts a sign by exerting a force along a rope of 250. N at an angle of 50.0owith respect to the ground. c)An aimless Physics teacher walks at 30.0 m/s [50.0o E of S]
5)A jogger runs 300 m [E] and then turns and runs 500m [S]. a)What is the total distancethat she ran? b)What is her displacement6)A pilot flies a plane 1.00 x 104km in a direction 30.0oN of W. a)How much further North is she than when she started? b)How much farther West is she than when she started? ?
