QUESTION FIVE

a. You came across a picture of three co-planar forces acting at a point, P. The first force is 200N and acting at 20° to the horizontal; the second 400N and acting at 165° to the horizontal; the third 500N acting at 250° to the horizontal.

Draw what you saw in the picture using an appropriate scale. Use protractor for the angles. AP[8 marks]

b. With the information in a); determine by resolution of forces

i. The magnitude of the resultant of the three co-planar Forces.

ii. The direction of the resultant of the three co-planar forces.

AP [7 marks]

c. A horizontal force with a mass of 100kg is being applied to a body to move it

at a uniform velocity through a distance of 20m in 8 seconds in the direction

of the force.

Determine the value

i.

The Force

ii.
