A uniform rod of length 180 cm is supported by a wire at a distance of X = 48.4 cm from its left end. When a mass of 187 g is placed on the left end of the rod, the rod is in equilibrium. This is shown in the diagram below. What is the mass of the rod, in units of grams?

Define conservation of energy in your own words be as specific as you can

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

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.
