An object is dropped from some height above ground. Air resistance on the object is given by Cv, where C = a coefficient of drag in units of N/ (m/s) and v = the object's velocity. Instructions: b)use newton second law and sum the forces on the mass in the y direction. Because v= negative and air resistance opposes motion. you must be careful of signs. Replace acceleration in the equation. d.)Seperate variables... put time on one side of the...

An object with cross section A is shot horizontally across frictionless ice. Its initial velocity is v0x at t0=0s. Air resistance is not negligible. A 1.8 m wide, 1.5 m high, 1700 kg car with a drag coefficient of 0.35 hits a very slick patch of ice while going 24 m/s . Air resistance is not negligible. If friction is neglected, how long will it take until the car's speed drops to 11 m/s ? To 5.0 m/s ?
