1) A car moves along a horizontal road. Be sure to include the friction of the road that opposes the forward motion of the car.
2) A sailboat is acted on by a force of 2000 N East. At the same time, the wind acts on the same sailboat with a force of 3000 N at 45° North of East
3 Two forces of 25 N and 45N act on an object. Their directions differ by 70°.
4.A force of 1600 N acts parallel to a ramp. The ramp has an incline of 20°.

While drawing free body diagram make the object as a small box , then using arrows mark the forces
1) let W be weight of car , N is normal reaction , F is forward Force on car and "f" is force of friction .
2) F1 = 2000 N , East , F2 = 3000 N , 45° North of East.
3) F1 and F2 are acting 70° apart
4) Let the Force F = 1600N is acting on a body of mass "m"
