Gce Model Questions Vol1 2021 Physics Question 11
Practice objective / multiple choice question 11 from the 2021 Gce Model Questions Vol1 Physics examination.
A 5.0 kg block is released from rest at the top of a 30° incline that is 3.0 m high. The coefficient of kinetic friction between the block and the incline is 0.20. At the bottom of the incline a horizontal spring of constant 800 N·m⁻¹ is attached, and the block compresses the spring until it momentarily stops. (i) Determine the maximum compression of the spring. (ii) The block is then lifted back to the top of the incline by a motor moving it up the incline at constant speed, taking 4.0 s to complete the ascent. Calculate the average power output of the motor.
