Neco Model Questions Vol1 2024 Physics Question 39
Practice objective / multiple choice question 39 from the 2024 Neco Model Questions Vol1 Physics examination.
A 5.0‑kg block is released from rest at the top of a 10‑m long incline that makes an angle of \(30^{\circ}\) with the horizontal. The coefficient of kinetic friction between the block and the incline is 0.20. Determine (a) the speed of the block at the bottom of the incline (in \(\text{m s}^{-1}\) to one decimal place), (b) the total work done by friction (in joules), and (c) the average power delivered by gravity during the descent (in watts, to the nearest whole number).
