Neco 2023 Physics Question 37
Practice objective / multiple choice question 37 from the 2023 Neco Physics examination.
A \(2\ \text{kg}\) block slides on a horizontal rough surface. A pulling force increases uniformly from \(0\ \text{N}\) at the start to \(30\ \text{N}\) after the block has moved \(5.0\ \text{m}\). The coefficient of kinetic friction is \(0.10\). The block starts from rest. (a) Calculate the work done by the pulling force. (b) Calculate the work done by friction. (c) Using the work‑energy theorem, find the speed of the block after it has traveled \(5.0\ \text{m}\). Give the speed to two significant figures.
