If the system shown in released from rest. Find the net workdone by tension in first one second `(g = 10 m//s^(2))`.
.

Text Solution

Verified by Experts

`a = ((m_(2) - m_(1))/(m_(1) + m_(2))) g =((3-2)/(2+3)) 10 = 2m//s^(2)`
`T = (2m_(1)m_(2)g)/(m_(1) +m_(2)) = (2xx 2xx3xx10)/(2+3) = 24 N`
for each block `S = (1)/(2) at^(2) = (1)/(2) xx 2 xx 1 = 1m`
`:. W_("net") = W_(1) + W_(2) = TS - TS = 0`.
