    Calculating Potential Energy of Spring at Point A on Incline

    A wooden block with mass 1.50 kg is placed against a compressed spring at the bottom of an incline of slope 30.0 degrees (point A). When the spring is realeased, it projects the block up the inline. At point B, a distance of 6.00 m up the incline from A, the block is moving up the incline at...

    Engineering Applying KVL and KCL in Electrical Circuits: A Comprehensive Guide

    For this question I was thinking about doing KVL around the entire circuit, or do Mesh in the individual loops. Any suggestions?

    Calculate Position & Acceleration Vectors of Bird in xy-Plane

    I notice that x=0, so there is no horizontal motion. What do they mean by birds altitude as it flies over x=0 after t=0, meaning whent t=1. Also so since x=0 I only focus on the y componet of the position vector, which is (ct^2)/2?

    Engineering Need help w/ circuit analysis

    Well, I could take KVL around the loop -Vx/8 + 6Ix + 6Ix - 1Ix=0 KVl around the lower right hand +32Ix -15Ix -1Ix= 0 = 16Ix=0. Then what?

    Calculate Position & Acceleration Vectors of Bird in xy-Plane

    Well, atiderviative will give me the position vector, but I don't know if I should plug in the values of a, b, etc. prior to me taking the antiderivative. Also I am not sure what form they are talking about. For the acceleration the derivative is needed. Not sure about the last question

    Calculate Position & Acceleration Vectors of Bird in xy-Plane

    A bird flies in the xy-plane with a velocity vector given by v(vector) = (a-bt^2)(i-vector) + ct (j-vector) , with a= 2.4m/s, b=1.6m/s^3,c=4.0m/s^2. The positive y-direction is vertically upward. At t=0 the bird is at the origin. Calculate the position vector of the bird as a function of...
