Auniform meter stick of mass $m$ has a half-filled can of fruit juice of mass $m$ attached to one end. the meter stick and the can balance at a point 21.2 cm from the end of the stick where the can is attached. when the balanced stick-can system is suspended from a scale, the reading on the scale is 2.58 n. calculate the mass of the meter stick.

111.6 g

Explanation:

Given

m + M = 2.58 / 9.8

= 0.2632 kg

When the can of fruit juice is balance from scale , we get following relation

M x ( 50 - 21.2 ) = m x 21.2 ( balancing the torque due to weight of scale and can about the balancing point )

M x 28.8 = 21.2 m

= 21.2 ( 0.2632 - M )

= 5.58 - 21.2 M

M ( 28.8 + 21.2 ) = 5.58

M = .1116 kg

= 111.6 g

the device is called “ rocket engine”

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
