A Block of Mass 5 Kg Slides Down a Frictionless

question 5

Multiple Choice

A block of mass 5 kg slides down a frictionless track from a height of 1.5 m. It collides with a second mass of 8 kg. The two blocks stick together and after the impact they begin to slide on a rough surface with a coefficient of kinetic friction of 0.65 until coming to rest. Calculate how far, d, the blocks slide on the rough surface.

• A) 3.4 m
• B) 0.22 m
• C) 2.3 m
• D) 0.34 m
• E) 0.16 m

Definitions:

Transform Faulting

A type of strike-slip fault where two tectonic plates slide past each other horizontally, typically found at mid-ocean ridges.

Mid-Ocean Ridge

An underwater mountain range, formed by plate tectonics, where new oceanic crust is created through volcanic activity.

Seafloor Spreading

A geologic process where new oceanic crust is formed at mid-ocean ridges and slowly moves away from the ridge, contributing to continental drift.

Subduction

The process by which one tectonic plate moves under another, sinking into the Earth's mantle.
