A car starting from rest travels 100 m in 5s with uniform acceleration Find the acceleration of the car ​

Answer»

nitial velocity ( u ) = 0distance ( s ) = 100 mtime ( t ) = 5 secAs we know that : -s = UT + 1/2 at²Substituting VALUES : -100 = 1/2 × a × 5 × 5100 = 25a/225a = 200 a = 200/25a = 8 m/s²Hence,acceleration = 8 m/s²▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃
