Answer to Question #1014 in Mechanics | Relativity for sabeen
The brochure advertising a sports car states that the car can be moving at 100.0 km/h, and stop in 37.19 meters. What is its average acceleration during a stop from that velocity? Express your answer in m/s2. Consider the car's initial velocity to be a positive quantity.
From the equations of the motion: v0 = at; t = v0/a; S = vo2/2a ; 100 km/h = 27.78 m/s; 27.782/2a = 37.19; a = 10.37 m/s
