Neco 2024 Physics Question 31
Practice objective / multiple choice question 31 from the 2024 Neco Physics examination.
A 5.0 kg block starts from rest at the top of a 6.0 m long smooth incline that makes an angle of \(30^{\circ}\) with the horizontal. The coefficient of kinetic friction between the block and the incline is 0.20. A motor attached to the block exerts a constant force up the incline, bringing the block to rest exactly at the bottom after traveling the full length in 5.0 s. Determine (a) the magnitude of the motor force, and (b) the average power delivered by the motor during the motion. Refer to the diagram.
