You are taking a picture of a distance mountain. You are 1.5 km away from the base. The image formed inside the camera is 2.3 cm high and the camera is 8.75 cm wide. What is the height of the moutnain?
What is the magnification of the image?

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.
