HELP ME!!!
HI GUYS
I AM LEARNING ABOUT ENERGY, WORK, ALL ABOUT CHAPTER 7 IN SERWAY. SO I HAVE THIS EXERCISE THAT I CAN NOT DO. PLS HELP ME. AN ALL ABOUT HOOKE
1-
a mass of 3 kg leaves from the rest and it slides by a slope without friction of 30 degrees, a distance d and makes contact with enemy with means nondeformed of despicable mass. the mass slides 0,35 additional ms when it reaches the rest momentarily and it compresses to the means (500 k = N/m) finds the initial separation between the mass and the means
2-a ball of 0,850 kg ties end of a cord of 1,8 ms of length and it is rotated in I circulate vertical.
during I circulate complete counting from any point, calculates the conducted total work on the ball by:
the tension in the cord? the gravity
repeat the part "to" for the movement throughout the semicircle that goes of beginning at the end of the trajectory.
I HOPE SOMEBODY CAN HELP ME PLS I NEED TO GIVE THIS ON TUESDAY I ALREADY DID 8 BUT THIS ARE THE LAST ONE.
THANKS A LOT.
