Question 3: In order to determine the force of friction and the coefficient of kinetic friction, you will use Vernier Video Analysis to find the acceleration of the cart. You will use the following video to determine these values. Download the following video and open up Vernier Video Analysis, and then import the video into the program. You need to begin your analysis after the hand is no longer pushing the cart and finish when the cart has come to...

1. A graph of the acceleration a, against the difference in mass 1 and mass 2 (delta m), with the sum of masses (Mtotal) held constant for the Atwood machine (like in question 2) gives: a) slope = g; Intercept on the y-axis = 0 b) slope = g/Mtotal; Intercept on the y-axis = 1 c) slope = g; Intercept on the y-axis = 1 d) slope = g/Mtotal; Intercept on the y-axis = 0 2. What is the acceleration...

‼️ Parts E-H Only, do not need A-D
The mass of block (m) is 30 Lb. The mass of block 4 () is 50 Lb, and the mass of block B (wa) is 75 Lb. You may neglect the masses of the pulleys, and you may assume that the blocks are initially at rest a) The equation(s) for position, velocity, acceleration, and displacement b) The displacement of the block at Bir A is pulled down a known distance of 3...

2 5. Consider the situation in the diagram. Block 1 has mass m, and is on a slope at an angle 0 from horizontal. Block 2 has mass m2. a. Find and expression for the acceleration of the blocks, ignoring friction. b. Could you have guessed this expression? c. If the kinetic friction coefficient for block 1 is uk, how does this change the equation?

Hi, please explai the answer for all three part of the quesitons,
espcially for part a, why can't you increase mass on both blcosk,
since the eqaution from work- energy theory proves that 1/2 m r'2 =
mgh , the mass doesn't really matter ??
