FORMULAS :Speed in km/hr × 5/18 = Speed in m/sec
And three Equation of Motion i.e. v = u + ats = ut + 1/2 a t^2v^2 = u^2 + 2as
Force = Mass × Acceleration_______________________________
Initial velocity = 90 km/hrInitial velocity in m/sec = 90 × 5/18Initial velocity (u) = 25 m/sec
Time (t) = 5 seconds
Final Velocity (v) = 0 because motorcycle is at rest finally
Using First equation of Motion,v = u + at0 = 25 + a × 5-25 = 5a
a = -5 m/sec ^2
=> Retardation = 5 m/sec ^2_____________________________
Retarding Force = Mass × Retardation
Retarding Force = 200 × 5
Retarding Force = 1000 N_____________________________
