Ch 3.2 Help
I will fill in the blanks as answers get solved but seeing as this is old I doubt anybody needs them.
Question 1: (1 point)
The xcomponent of a velocity vector is 4.348 m/s and the ycomponent is 3.19 m/s. What is the magnitude of the velocity (sheet 3,4 and 5)?
How to solve:
Question 2: (1 point)
The magnitude of a velocity vector is 6.011 and its direction is 152.8 degrees (measured counter clockwise from the positive xaxis). What is the ycomponent (sheet 3,4 and 5)?
How to solve:
Question 3: (1 point)
The xand ycomponents of two vectors A and B in the notation (x, y) are (5.169 , 2.984 ) for A and (6, 0.784 ) for B in arbitrary units. What is the direction of the vector C = (A  B) measured as an angle between the vector C and the positive xaxis in counter clockwise direction (sheet 6  convince yourself with the graphical "head to tail" method that your result makes sense, see sheet 7,8; such a graphical evaluation will be required in midterm 1 )?
How to solve:
Question 4: (1 point)
A person runs on a slowly moving trailer with 1.2362 m/s toward the back end of the trailer. What is the velocity of the person relative to the ground if the trailer has a velocity of 0.6276 m/s (sheet 13,14,14')? The direction in which the trailer moves is the positive xaxis.
