Note: The answer suppose to be

A) 2.8 X 10³ J

B) 2.1 x 10³J

.....the line where the 13.5 is kind of threw me off.... I'm assuming its 13.5 rather than 14.

Thanks

a) W = (1/2)(3)(400) + (7 - 3)(400) + (1/2)(10 - 7)(400)

= 2800 J

b) W = W_0-10 + W_10-15

= 2800 + (1/2)(12 - 10)(-200) + (13.5 - 12)(-200) + (1/2)(15 - 13.5)(-200)

= 2150 J

I think it can help you.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
