5. Your friend is in Physics 12 and has just completed a lab where a low friction cart is rolled down a ramp at various angles and the acceleration is determined. Your friend offers you their results in the form of the graph below. Acceleration of a t e of the Angle of the Ramp Acceleration, a (m/s') equation of best-fit line: a = 9.94 m/s' sin 0 0.2 0.4 0.6 0.8 Sine of Angle, sin e 3. You revisit the scene of the accident and carefully measure the angle of the road. It turns out to be an angle of 40 below the horizontal (we say angle of declination ). Based on your graph above , determine the acceleration due to gravity responsible for pulling the car down the ramp Acceleration down the ramp : (show all work ) a =
