Question

A racing car has uniform acceleration of 2m/s square what distance will it covers in 30 second after the start

Answer 1

simply apply newtons equations for uniform acceleration

here distance is equal to displacement as motion is uniform acclrted motion means 1d motion

so,     s = ut + 1/2at square

=>     s = 30*0 + 1/2*30*30

=>      s = 450

Answer 2

s = at² / 2

s = 2 × 30² / 2

s = 900 m
