Tom enlists the help of his friend John to move his car. They apply forces to the car as shown in the diagram. Here IF₁1 = 442 N, IF₂1 = 340 N and friction is negligible. Mass of the car = 3.50 x 10³ kg, 0₁ = 12.0°, and 2₂ = 25.0°. The diagram below shows the top view of the car which is in the x-z plane (horizontal plane). T F₁ (a) Find the resultant force exerted on the car. (Express your answer in vector notation.) Fnet = 530.92k + 170.56j X Did you consider the components of the forces in the x and z directions? Review rules for vector addition. N (b) What is the acceleration of the car? (Express your answer in vector notation.) a= 0.223 X How is the net force on an object related to its acceleration? m/s²2

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
