7.2 This is a sketch with free body diagrams of a simple Atwood's Machine. If M1 (blue) is heavier than M2 (orange) The Atwood Machine Fre Body Diagrams for Mi and M2 Puttey M2 M1 M2g Mag Mi Equations of Motion: M2 7.2.1 Which will have greater value of acceleration? Select One 7.2.2 Why? 72.3 What will be the direction of the velocity in Mi (blue)? Select One 7.2.4 What will be the direction of the acceleration in M1 (blue) Select One 7.2.5 What will be the direction of the velocity in M2 (orange)? Select One 7.2.6 What will be the direction of the acceleration in M2 (orange)? Select One 7.2.7 Compute the value of the acceleration in either mass. Suppose M is 200 grams and M2 is 70 gr. As you can see in the picture, there are 2 equations for 2 unknowns. Final hint: Both masses have the same acceleration. show your work.

Explanation / Answer

7.2.1 both will have same value of acceleration.

7.2.2 because both masses were connected by a string and string is unstretchable.

so both block will have same acc.

7.2.3: downwards

7.2.4 : downwards

7.2.5: upward

7.2.6 : upward

7.2.7 : 0.200g - T = 0.200 a

and T - 0.070g = 0.070 a

adding , 0.200g - 0.070g = (0.200 + 0.070) a

a = 4.72 m/s^2
