1 The magnitude of a vector... a Must always include direction b Can be less than one of its components d must include unit vectors 2 Given the vector A 4.00 +7.00j, find the magnitude of the vector. c Can never be less than one of its components a 5.74 b 3.31 c 8.06 d 65.00 Based on the graph shown for a moving particle at the right what is the instantaneous acceleration of the object at 25.0s? x (m) 3 40 30 20 a 25.0 m/s b 9.8 m/s2 0.5m/s2 0.0 m/s2 c 10 d t (s) 0 10 20 30 40 50 4 The graph to the right shows the position of two cars over Car 1 time. At which point do the cars pass one another? D E Car 2 b B 5 A cannonball is fired horizntally from the ton of li ThExplanation / Answer
Q: 1 c ) can never be less than one of its components
Q:2 Magnitude of A = sqroot (4^2+ 7^2)=8.06
Q: 3 let's look at the velocity
V1= ( 20-10m)/15 =0.67m/s
V2 = ( 30-20)/ 15 = 0.67 m/s
instantaneous acceleration at t= 25 seconds = 0
