Problem 3 [35 pts): Potential energy can be expressed using the following equation: E=m*g*h (1) Where:...
Do not assume a constant g for this problem. The gravitational potential energy of a 1 kg object on the earth's surface is -6.28e7 J. How much work is required to lift that object to a height of 5e6 m? GM = 4e14m^3/s^2. Radius of earth = 6.4e6 m.
3. The potential energy of an object is given by P=m.g.h, where m is the mass, g is the gravitational constant (9.81m/s), and h is the height of that object above some reference point. If we measure m and h, as well as their uncertainties om and Oh, and we know the value of g, which is a constant, we want an algebraic expression for the uncertainty on the potential energy, op. (a) First, lets break this up into P...
the formula for potential energy is p= mgh, where Pis potential energy, m is mass, g is gravity, and h is height. which expression can be used to represent g?1 p-m-h2 p-mh3 p/m0-h4 p/(mh)
To understand the relationship and differences between electric potential and electric potential energy. In this problem we will learn about the relationships between electric force F⃗ , electric field E⃗ , potential energy U, and electric potential V. To understand these concepts, we will first study a system with which you are already familiar: the uniform gravitational field. F⃗ (z) =−mgk^ 1)Now find the gravitational potential energy U(z) of the object when it is at an arbitrary height z. Take...
Consider the Conservation of Energy Equation: where E is energy in [kJ is heat in [kJ, W is work in kJ is mass in [kg], h is enthalpy in [kJ/kg], V is velocity in [m/s], g is gravitational acceleration is m/s2] and z is height in [m]. Taking the derivative of a variable with respect time time is simply dividing the base variable unit by time. Determine, in base units (kg], [m], [s) the following: a) The units for the...
Conservation of Energy Ranking Task Six pendulums of various masses m are released from various heights h above a tabletop, as shown in the figures below. All the pendulums have the same length and are mounted such that at the vertical position their lowest points are the height of the tabletop and just do not strike the tabletop when released. Assume that the size of each bob is negligible. Rank each pendulum on the basis of its initial gravitational potential...
answer all please Problem 1. A block of mass m = 735 g is located on an incline which makes an angle of 40 with the horizontal The friction coefficient between the block and the incline is K = 0.21. The block is released and it is let slide down the incline. (a) Draw a free body diagram and identify all forces acting on the block. Find the acceleration of the block (b) If the block moves d = 0.42...

Hand In Problem 2 A solid globe of mass M and radius R can rotate about its axis. A block of mass m is attached by a massless-string/pulley system as shown. As the block falls it causes the globe to spin. If the block starts at rest, at what speed does the block hit the ground after it falls a distance h?
