WebAug 11, 2015 · Now, the relative velocity of car B approaching your car is given as. V B − V A. Now, at any moment, let d be the distance between your car A & car B behind you then the time taken by car B to overtake you is. = distance between car A & B relative velocity of car B w.r.t. car A. = d V B − V A. WebThe change in velocity is v – u, which is 30 – 10 = 20 m/s. The acceleration is the change in velocity ÷ time, which is 20 m/s ÷ 4 s = 5 m/s 2.. Question

WebThe Math / Science The formula for the velocity based on the length of skid marks is: v = √30⋅ L⋅ f c v = 30 ⋅ L ⋅ f c where: v = initial velocity L = Length of Skid Marks fc = friction coefficient (0.05 for very slippery to 0.9 for ultimate breaking) Braking Coefficient The Braking Coefficient is a coefficient of kinetic friction. WebSpeed (KMH) = ( ( (Engine speed as RPM / Gear ratio / Final drive ratio) × Tyre circumference) / 1000000) × 60 Speed Speed (MPH) = ( (Speed KMH) × 0.62 × 100) / … cohasset apartments
