3. [SFHS99 4.P.22.] An 1680 kg car is moving to the right at a constant velocity of 2.94 m/s.
(a) What is the net force on the car?
wrong check mark N
(b) What would be the net force on the car if it were moving to the left?
in Newtons = ??
4. [SFHS99 4.P.23.] A freight train has a mass of 5.5 107 kg. If the locomotive can exert a constant pull of 15 105 N, how long would it take to increase the speed of the train from rest to 85 km/h?
in seconds =??
thanks alot
