A forklift raises 300kg of load through a distance of 12m in 15sec. Determine? – NABTEB QUESTION

(i) The force required to lift the load
(ii) The work done by the forklift
(iii) The power dissipated by the forklift in KW. (Take g = 10m/S²)

F = ma; where a = g
= mg
= 300 x 10
= 3,000N

(ii) Work done by the forklift in 15secs
work done, W = Force x Distance
= f x s
= 3,000 x 12
= 36,000J

(iii) The power dissipated by the fork lift in kw
Power, P = work done/time taken = W/t

= 36,000/15 = 2400w

= 2.4kw
