A man of mass 80kg stands in a lift. If the lift moves upwards with acceleration 0.5\(ms^{-2}\), calculate the reaction from the floor of the lift on the man. \([g = 10ms^{-2}]\)
\(\text{Net force = Upward force - weight}\)
\(ma = F - mg \implies F = ma + mg \)
\(F = (80 \times 10) + (80 \times 0.5) = 800 + 40 = 840N\)
