Question 2 Incorrect Experimental data for the motion of a particle along a straight line yield measured values of the velocity v for various position coordinates s. A smooth curve is drawn through the points as shown in the graph. Determine the acceleration a of the particle when s 25.0 ft. v, fusee 2 10 15 20 25 25 30 8, ft 1.008 Answer: a = the tolerance is +/-5% ft/sec²
