Neco Model Questions Vol1 2018 Physics Question 22
Practice objective / multiple choice question 22 from the 2018 Neco Model Questions Vol1 Physics examination.
A \(5.0\ \text{kg}\) block is released from rest at the top of a frictionless incline that is \(10\ \text{m}\) high and makes an angle of \(30^{\circ}\) with the horizontal. At the bottom of the incline the block reaches a horizontal rough surface with coefficient of kinetic friction \(\mu_{k}=0.20\) and then compresses a spring of force constant \(k=800\ \text{N m}^{-1}\) until it momentarily comes to rest. (i) Find the maximum compression \(x\) of the spring (in metres, to two decimal places). (ii) Assuming the block decelerates uniformly while compressing the spring, calculate the average power delivered by the block during the compression phase (in kilowatts, to two decimal places).
