    How Much Stopping Distance Does Sally Need on Her Bicycle?

    ok so Force friction is equal to -340 Newtons divided by the mass of 95 kg would make the acceleration -3.6 meters per second squared...but then my initial velocity has to be wrong because velocity final is 0 but if i input all of my values 800 meters per second for initial velocity and -3.6...

    How Much Stopping Distance Does Sally Need on Her Bicycle?

    sorry! ok so anyways 800 meters per second is initial velocity and wait the mass is 95 kilograms... so you have coefficient of friction = gravity divided by acceleration? so then you just have gravity divided by the coefficient so then acceleration = 27.2 meters per second squared and then how...

    How Much Stopping Distance Does Sally Need on Her Bicycle?

    what are you talking about there is no 50 km/hr...but i did convert the 50000 meters per hour to meters per second and i got 800 meters per second and then that would be initial velocity and then force friction equals mass times gravity right? but then i have initial and final velocity, the...
