Give reason: “One should take short steps rather than long steps when walking on ice”.
Let R represents the reaction offered by the ground. The vertical component R cos balance the weight of the person and the horizontal component R sin to walk forward. Normal reaction = R cosϴ Friction force = R sin ϴ Coefficient of friction sin tan cos R R θ µ θ θ = = In along step, ϴ is more and tan shipping in along step.
