PHYS 1051 Midterm: PHYS 1051 Spring 2012 Term Test 1
Document Summary
Instructions: there are four questions, each consisting of short theory part and a problem solving part. Answer all the questions, show all your work: do not erase or whiteout your answers. [2. 5 points: two vectors, p and q are shown in the picture below, with p =5. 00 units and q=6. 33 units and angles =36. 9o and =288. 4o, write vectors p and q in unit vector notation. [4 points: determine the magnitude and direction of vector b = p + q . [3 points: determine the magnitude and direction of vector product of c = p q . Question ii: draw the graph showing the kinetic energy k of the simple harmonic oscillator as a function of displacement from equilibrium x. [2. 5 points: figure below shows the position versus time graph for a 1. 00 kg block oscillating on spring with spring constant 20. 0 n/m, determine the angular frequency of the oscillation. [2 points: determine the phase constant of the motion.
