The moon's mass is 7.35 × 1022 kg, and it moves around the earth approximately in a circle or radius 3.82 × 105 km. The time required for one revolution is 27.3 days. Calculate the centripetal force that must act on the moon.
KEY. Kinetic Energy Practice Problems. 1. What is the Kinetic Energy of a 150 kg object that is moving with a speed of 15 m/s? KE = 1⁄2 mv2. KE = ? m = 150kg v = 15m/s . KE = 1⁄2 (150kg) (15 m/s)2. KE = 1⁄2 (150kg)(225) KE = 16875J. 2. An object has a kinetic energy of 25 J and a mass of 34 kg , how fast is the object moving? KE = 1⁄2 mv2.
This collection of problem sets and problems target student ability to use momentum, impulse, and conservations principles to solve physics word problems associated with collisions, explosions, and explosive-like impulses.
Solution. Let nb, nr, ny and ng be the numbers of blue, red, yellow and green buttons respectively. Also let N = nb + nr + ny + ng be the total number of buttons. We need to convert the information given in the question into mathemat-ical statements.
Physics 24 Problem Set 1. Harry Nelson. due Wednesday, January 18. Please make your work neat, clear, and easy to follow. It is hard to grade sloppy work accurately. Generally, make a clear diagram, and label quantities. Derive symbolic answers, and then plug in numbers after a symbolic answer is available. Purcell 4.3. Purcell 4.4. Purcell 4.6.
These problems allow any student of physics to test their understanding of the use of the four kinematic equations to solve problems involving the one-dimensional motion of objects. You are encouraged to read each problem and practice the use of the strategy in the solution of the problem.
