Waec Model Questions Vol1 2019 Physics Question 41
Practice objective / multiple choice question 41 from the 2019 Waec Model Questions Vol1 Physics examination.
A block of mass 2.0 kg is released from rest at the top of a smooth inclined plane 5.0 m long making an angle of 30° with the horizontal. At the bottom of the plane a horizontal spring of force constant 400 N·m⁻¹ is fixed; the spring is initially uncompressed. The block compresses the spring by 0.10 m and momentarily comes to rest. Assuming kinetic friction acts over the whole incline, determine (a) the coefficient of kinetic friction μ between the block and the plane, and (b) the speed of the block after it has travelled 2.0 m down the incline.
