Question 29 GCE_MODEL_QUESTIONS_VOL1 • 2023 • PHYSICS • objective

A 2.0 kg block starts from rest at the top of a smooth 5.0 m long incline that makes an angle of 30° with the horizontal. At the bottom it reaches a horizontal rough surface (coefficient of kinetic friction \(\mu_k = 0.20\)) and compresses a spring of constant \(k = 800\) N·m⁻¹ until it momentarily comes to rest. (i) Find the speed of the block at the bottom of the incline. (ii) Determine the maximum compression of the spring. Give your answers to three significant figures.

Answer Options

Correct Answer A. Speed at bottom: 7.00 m s⁻¹; maximum spring compression: 0.345 m
B. Speed at bottom: 6.50 m s⁻¹; maximum spring compression: 0.300 m
C. Speed at bottom: 7.00 m s⁻¹; maximum spring compression: 0.250 m
D. Speed at bottom: 7.50 m s⁻¹; maximum spring compression: 0.380 m
Correct Answer
A
Correct Option:
Speed at bottom: 7.00 m s⁻¹; maximum spring compression: 0.345 m
