A car is driving on a level highway. It is acted upon by the following forces: a downward gravitational force of 12 kN, an upward contact force due to the road of 12 kN, another contact force due to the road of 7 kN directed West, and a drag force due to air resistance of 5 kN directed East. What is the net force acting on the car?
1 answer
force in x-direction Fx:5cos0+12cos90+7cos180+12cos360=10kN Fy:5sin0+12sin90+7sin180+12sin360=12kN Net force=sqrt(10^2+12^2)=15.6kN
