CLICK HERE TO SEE QUESTION 6 QUESTION 6 6.1 A 3 kg trоlley is аt rest оn а hоrizontаl frictionless surface. A constant horizontal force of 10 N is applied to the trolley over a distance of 2,5 m. When the force is removed at point P, the trolley moves a distance of 10 m up the incline until it reaches the maximum height at point Q. While the trolley moves up the incline, there is a constant frictional force of 2 N acting on it. 6.1.1 Write down the name of a non-conservative force acting on the trolley that does work on the trolley as it moves up the incline. (1) 6.1.2 State the WORK-ENERGY THEOREM in words. (2) 6.1.3 Use the work-energy theorem to calculate the speed of the trolley when it reaches point P. (4) 6.1.4 Calculate the height, h, that the trolley reaches at point Q. (5) 6.2 A farmer uses an 8 W electric pump to raise water from a river in order to fill the irrigation channels that keep the soil in his fields moist. Every minute, the pump raises 12 kg of water, at a constant rate, through a vertical height of 3 m. 6.2.1 Calculate the power output of the motor. (4) 6.2.2 Calculate the percentage efficiency of the motor. (2) [18]

Hy swaai op 'n tak na 'n mandjie vrugte wat op die grond is, getoon deur posisie B hieronder. Terwyl hy swaai, gryp hy die vrugtemandjie en gaan voort om opwaarts teen 'n muur te swaai, getoon deur posisie C hieronder. Die massa van die volwasse aap is 5,90 kg en die massa van die vrugtemandjie is 800 g. Die diagram hieronder toon 'n vereenvoudigde prentjie van die beweging. 5.1.1 Noem die beginsel van behoud van meganiese energie. (2) 5.1.2 Gebruik bogenoemde wet om die spoed van die volwasse aap te bereken wanneer die aap die vrugtemandjie by B bereik. (4) 5.1.3 Noem die wet van behoud van momentum. (2) 5.1.4 Bereken die spoed van die aap en die vrugtemandjie onmiddellik nadat die aap die mandjie opgetel het en hulle saam van posisie B begin wegbeweeg. (4) 5.1.5 Verduidelik waarom die hoogte van die muur by posisie C laer moet wees as die hoogte van die tak by posisie A. (Geen verdere berekeninge word vereis nie.) (2) [14]
