Three Blocks Consider the scenario below with three blocks attached by ropes to each other over two pulleys (P and P) In this situation, m2 > mi and mi > m3, there is friction between the harizontal plane and block 2 (), and black 2 is observed to travel at a constant speed. Assume that the pulleys spin without friction on their axles and have negligible mass. Select the appropriate statements to complete the following sentences. Fqua to Ti4 is. mig. Equal toTs3 is... m39 The magnitude of the net force on m2 is T42-T25. s. m 3 accelerates upward 42T14 T42 T25 Greater than Less than Equal Tries 2/15 Preyjous Trles

Explanation / Answer

block travels with constant speed hence a = 0

on m1: Fnet = m1g - T14 = 0

T14 = m1 g

Ans: Equal to

-----------------

Fnet = T53 - m3 g = 0 on m3

T53 = m3 g

Ans: Equal to

----------------

net force on m2 is T42 - T25 - f where f = frictional force

Ans: False

-----------------------

system is moving with constant speed, a = 0

Ans: false

-------------------

T42 = T14 = m1 g

Ans: equal to  
----------------

T42 = m1 g  

T25 = m3 m g

m1 > m3

hence T42 > T25

Greater than
