Neco Model Questions Vol1 2019 Physics Question 4
Practice objective / multiple choice question 4 from the 2019 Neco Model Questions Vol1 Physics examination.
A 5.0 kg block is released from rest at the top of a 30° incline that is 8.0 m long. The coefficient of kinetic friction between the block and the incline is 0.15. After reaching the bottom, the block moves onto a horizontal surface (same \(\mu\)) and compresses a spring of constant \(k = 1200\,\text{N·m}^{-1}\) until it momentarily stops. (a) Calculate the maximum compression of the spring (in metres, to three significant figures). (b) Determine the average power delivered by the spring during the compression phase (in kilowatts, to two decimal places).
