6. A truck driver on the top of a hill lets his hand brake off in neutral gear so that his truck drifts 150m down the hill to a level road. Near to the bottom he realizes that he cannot stop and will need to use the emergency slip road track at the bottom filled with sand 150 m 30⁰ Emergency sand pit The distance down the hill from the top is 150 m and it has a slope of 30⁰. The speed of the truck down the slope as it hits the sand will be about: A. 22.6 ms-¹ B. 38.3 ms-1 C. 54.2 ms-1 D. 61.3 ms-1

Expert Solution
Step 1: Conceptual Introduction

The equation of motion that relates the initial velocity, final velocity, acceleration and distance traveled is given by -

      v squared equals u squared plus 2 a s

    where v is the final velocity

               u is the initial velocity

               s is the distance traveled

               a is the acceleration
