Neco 2019 Physics Question 26
Practice objective / multiple choice question 26 from the 2019 Neco Physics examination.
A \(5.0\ \text{kg}\) block is released from rest at the top of a \(30^\\circ\) incline that is \(8.0\ \text{m}\) long. The block slides down, compressing a spring of constant \(k = 200\ \text{N·m}^{-1}\) by \(0.20\ \text{m}\) and then comes to rest. The coefficient of kinetic friction \(\mu\) between the block and the incline is unknown. (i) Determine \(\mu\). (ii) Find the average power delivered by gravity to the block during its motion down the incline. Take \(g = 9.8\ \text{m·s}^{-2}\).
