Question
estion 1 Not yet rowernd Marked out of Two moons orbit a planet. The first moon is 2 10 m from the center of the planet and has a mass of 4.8 x 100 kg while the second moon is 4 10m from the center of the planet and has a mass of 2 x 1022 kg. If the planet has a mass of 33 x 102s kg and its center is the 0 value of the coordinate system how far is the center of mass of the planet and 2 moon system from the center of he planet in kilometers? Answer at yet swered larked out of The impulse imparted to an object that experiences an average force of 3.6 x 10% N is 6.5 x 101. How long does the force interact with the object? Answer on 3 What is the speed of an object that has a mass of 400kg and a momentum of 6000 kgm/sec? d out of Answer tion An object of mass 0 2kg is fired upward at a speed of 35m/sec. What is its change in potential gyny? Markad out of Answer Question 5 Not yet An object has a total energy of 12.J. What is its kinetic energy at position x7m if its Potential energy there is &J;? Marked out of AnswerExplanation / Answer
2
Using force -impulse relation
Ft= impulse
t= 65/(3.6*10^5)= 1.806*10^-4 seconds
------
3. V= P/m= 6000/400= 15 m/s
------
4.change in potential energy= kinetic energy given initially
=0.5* mv^2
= 0.5*0.2*35*35= 122.5 J
-------
5.
K.E= total energy - PE= 12-8= 4J
