A car starts from rest and acceleratesuniformly over a time of 5.21 seconds for adistance of 110 m. Determine theacceleration of the car. |
Answer» Given: d = 110 m t = 5.21 s vi = 0 m/s Find: a = ??d = vi*t + 0.5*a*t2110 m = (0 m/s)*(5.21 s)+ 0.5*(a)*(5.21 s)2 110 m = (13.57 s2)*a a = (110 m)/(13.57 s2) a = 8.10 m/ s2 |
