Igcse Model Questions Vol1 2025 Physics Question 28
Practice objective / multiple choice question 28 from the 2025 Igcse Model Questions Vol1 Physics examination.
A \(2.0\ \text{kg}\) block starts from rest at the top of a smooth incline that is \(5.0\ \text{m}\) long and makes an angle of \(30^{\circ}\) with the horizontal. At the bottom of the incline the block reaches a rough horizontal surface where the coefficient of kinetic friction is \(0.20\). The block slides across this surface for \(2.0\ \text{m}\) before compressing a spring of force constant \(800\ \text{N m}^{-1}\) until it momentarily comes to rest.\n\n(a) Find the maximum compression of the spring.\n(b) If a motor later lifts the block vertically back to the top of the incline in \(4.0\ \text{s}\), what is the average power output of the motor? Give your answers to three significant figures.
