Vectors Practice
1. Two force vectors act on the same object one is 80N north, and the other is 130N west. What is the resultant of
these 2 vectors?
2. A river flows south at 15 m/s. A boat travels east across the river at 18 m/s.. What is the resultant velocity of the
boat?
3. A force of 80N is directed at 50o above the horizontal. What are the horizontal and vertical components of this
force?
4. An airplane flies at 300mph due east while a wind blows at 50 m/s at 30 degrees north of east. What is the
resultant velocity of the plane?
5. A 200kg crate sits on a ramp inclined at an angle of 35 o. Find the perpendicular and parallel forces acting on the
crate.
6. A boat sails directly east at 20m/s while an ocean current pushes it at an angle of 45o northeast at a speed of 5m/s.
Find the overall velocity of the boat.
7. A 2100kg car sits on a hill with an incline angle of 25 o. Find the perpendicular and parallel forces on the car.
