Answer» scooter MOVING at a speed of 10m/s is stopped by applying BRAKES which produce a uniform ACCELERATION of -0.5 m/s² .To findHow MUCH distance will be covered by the scooter before it stops ?SolutionInitial speed (u) = 10m/sFinal velocity (v) = 0Acceleration (a) = -0.5 m/s² Distance covered (s) = ?According to third equation of motion→ v² = u² + 2as→ (0)² = (10)² + 2 × (-0.5) × s→ 0 = 100 - s→ s = 100 mHence, distance travelled by scooter is 100mNote : (-) minus shows retardation |
