Part A - Pulling force F : calculate its x- and y- components. Learning Goal: lication of Newton's Laws Keep 2 digits after the decimal point. Unit is Newtons. Separate answers by commas. F Fr, Fy Submit Request Answer A block is being pulled by a force F up a smooth incline (without friction) which makes 330 relative to the horizontal.. (We will revisit this problem and include Part B - friction). The block's mass is m = 8.4 kg , The magnitude of the gravitational acceleration is 9.80 m/s' . The force F is parallel to the incline and its magnitude is F = 70.0 N. The normal force F'N : its magnitude is NOT automatically known. (A common mistake is to think FN is always equal to the magnitude of the weight.) Here we use a space holder for magnitude FN- Which of the ollowing is the correct way to write its x- and y- components of FN? Keep 2 digits after the decimal point. Unit is Newtons. Separate answers by commas. O FN, X = FNsin330 FN, y= FN COS330 OFN, X = 0 FN.y= - FN OFN, X = FN, FN.y= 0 OFN. X = 0 FN, y= FN O FN. X = FNCOS330 FN. y= FN Sin330 Submit Request Answer Part C - Remember: weight is a force, which is a vector. Calculate its x- and y- components. Pay attention to the geometry, and what angle to use, which trignometrical functions to use, and the signs of the components. Keep 2 digits after the decimal point. Unit is Newtons. Separate answers by commas. weight vector Wz. Wy = Submit Request Answer Now the table on the right side of the figure is complete with FN as a space holder. You can write up EFz and EF,, with FN as a space holder. You will apply Newton's Laws (1st or 2nd) Part D - The physical situation is that the block slides up the incline (along the x axis). You can find the magnitude of FN. If you don't know how, open the "hints". View Available Hint(s) magnitude FN = Submit Part E - Now apply Newton's 2nd Law in the x- axis to find the block's acceleration ax up the inicine. Keep 3 digits after the decimal point. Unit is m/s2 m/s? Submit Request Answer Part F - New situation 1: While the block is moving up the incline, the pulling F is reduced to half of its original value, Fnew = 35.00 N . Find the new acceleration along the x axis. Keep 3 digits after the decimal point. Unit is m/s O E
