just need d and e. thank you 6. Consider a head-on collision between two pucks, T = 0.5 kg and m = 0.3 kg in the image below. V2 The puck m, is initially travelling in the +x direction with velocity o, = +10m/s, and m, is initially travelling in the x direction with velocity = -3m/s. The two collide with a perfectly elastic collision along the x-direction. (a) What is the speed of the center of mass of the...
1-4 using Work-Energy Theorem/KE and PE thank you! not 1. An object of mass 0.5kg is projected from ground at 40m/s. Find the work done by gravity on the object, when it is at (a) 10m above the ground -49 Joules (b) 15m above the ground.- 73.5 Joules (c) Find the potential energy of the object in (a) and (b) relative to the ground. PE-mgh 49 J/73.55 2. A block of is sliding down a slope as shown in the...
please do all abcde and show steps. thank you! they are very confusing to me. 3.) Vectors are useful in physics and engineering. Force is one example of a vector quantity. Definition. If several forces are acting on an object, the resultant (net) force experienced by the object is the vector sum of these force. Below is information about two forces acting on an airplane. Force 1: Suppose that the wind is blowing 45 degrees Northwest at a speed of...
Question 8 please-show all work You are building a mobile. It is connected to the ceiling by a rope. The hanging weights are attached to a massless beam. Use L = 0.25 m, D = 0.5 m, M_1, = 1 kg and M_2 = 1.5 kg. You have a third mass M_3 = 2 kg. Determine the tension in the rope connecting the beam to the ceiling and the location where you attached M_3 if you correctly placed it so...
I have the answers to part a, b and d but please show all work. a)0 , (b) n=1949 , (d) 486N 8. Loading Ramp A mechanic pushes a heavy toolbox up a ramp at constant velocity. The toolbox has high-quality wheels and can be assumed to roll without friction. The ramp angle is 14° with respect to horizontal. The mass of the toolbox is 205 kg. The mechanic pushes on the toolbox in a direction which is parallel to...
Recitation Work - 5 In order to get full credit, you need to show all your work. question 1. A force Fx = cx^3 (c = 3.0 N/m^3) acts on an object with mass 40 kg that is sliding along a rough horizontal floor (x-axis) with coefficient of kinetic friction of 0.2. A) What is the work done by the force Fx on this object as it slides from x1 = 0.0 m to x2 = 6.0 m? B) What...
Please complete a,b,c,d show all work and explain please Physics 15 Due: FRIDAY 3, 2017 arch Roster No. Paper Homework #6 For multiple choice questions. circle the one best answer or letter (unless more than one answer is asked for your work on free response questions. Be sure to use proper units and significant figures in your final answers. organization and neatness count, too. Do NOT use red please reserve that color for grading. 1. Suppose that two workers simultaneously...
Can I get help with these questions please show all work thank you If you throw a ball straight up at 118 ms bow high will it go? a 11.5 m b) 0.29 m c) 0.42 m d) 7.1 m Given a position function x(t) = -5t^+ 14.2t^3 - 6, what is the acceleration at time t = 1.5 s? a) 69.2 m/s^2 b)-72.3 m/s^2 c) 150 m/s^2 d) -211.5 m/s^2 If a pulls straight up on a 350 kg...
Please try to answer all questions and show work. Thank you. 1. A baseball player is warming up and tosses a ball straight up into the air. The ball travels up until it reaches some maximum height, and then falls back down to the player's hand. If we neglect air resistance, then the magnitude of the acceleration of the ball is? A. largest the moment after it leaves the players hand. B. smallgst the moment after it leaves the player's...
