NEED ASAP A crayon’s image appears to be 23 cm behind the surface of a convex mirror.
a. If the mirror’s focal length is - 46 cm, how far in front of the mirror is the crayon positioned?
b. Draw a ray diagram for the situation.
c. What is the magnification of the image?
d. Is your ray diagram consistent with your math? Explain.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
