Hello your question has some missing part attached below is the missing part
How much work is done by the cog system on the cars?
<em>answer</em> : 2.053 * 10^7 J
Explanation:
Total weight of car ( wT ) = 5900 * 29 = 171100 N
mass of car ( mT ) = wT / g = 171100 / 9.81 = 17459.18 kg
Hence <u>work done by the cog system on the cars</u>
W = ( KE + PE
) - ( KE
+ PE
)
= ( 1/2 mv^2 + mgh ) - ( 0 )
= ( 1/2 * 17459.18 * 0.50^2) + ( 17459.18 * 9.81 * 120 )
= 2.053 * 10^7 J
