16. MULTIPLE CHOICE 2014
• With multiple choice questions. Generally not a lot of
working is needed. Look at the options logically.
17. The circle has centre at (3, 2) and radius of 2.
Options D and E will just touch.
Other options are perpendicular bisectors.
C is above the circle.
A is close to touching
But B will pass through the circle
18.
19. a(t) = 6cos(2t) i - 8 sin(2t) j
Max is 10 (use calculator)
Max Force is 50 N
25. Line joining points has one intersection with the circle
There is a lot of understanding in circles & trig
identities in this solution. You could find the
equation of the line and simultaneous with circle to
find discriminate =0. But long option.
