Practice Problems



1
A force of newtons is applied to a rope which makes an angle of 20 degrees with the horizontal. Calculate the horizontal component of the force.

2
What is the vertical component of the force in problem 1?

3
A car moves due North for meters and then due West for meters. Find the magnitude of the resultant displacement of the car.

4
A force of newtons acts due East on an object. What is the magnitude of the resultant force if the frictional force is 27 newtons?

5
A plane travels due Northeast (that means an angle 45 degrees North of due East) at miles/hour. What is the magnitude of the Eastward component of the plane's velocity?
