Question: 1a a 1500 kg automobile accelerates from zero to sixty...

Question details

1a.) A 1500 kg automobile accelerates from zero to sixty miles per hour (0 to 27 m/s) in 8 speed (V) and tho dconstant acceleration and no friction. Graph the power required (P), the speed (V) and the distance traveled (x) versus time (t). Find numeric values at t-8 seconds At time, t-8 seconds, F P (kw) m. kW, V = 27 m/s, x = V (m/s) x (m) t (s) t (s) L t (s) 0 What do the slopes represent? What do the areas under the curve represent? 4 8 1b.) Repeat assuming constant power in place of constant acceleration. (PAKE/At-68.3 kW) At time, t = 8 seconds, F =- N, a =ー m/s, V = 27 m/s, x= F (N) V (m/s) x (m) HINT Newtons laws of Mechanics F=ma a dVidt, integrate a to get V V = dx/dt, integrate v to get x -t (s) t(s) L 4 4 What do the slopes represent? What do the areas under the curve represent?
