I really need help on this question. I need it to be solved correctly because I have one more try. Thank you.

The diagram below is a top-down view of two children pulling a 13.8-kg sled along the snow. The first child exerts a force of [F1| = 11.0 N at an angle 01 = 45.0 counterclockwise from the positive x direction. The second child exerts a force of [F2| = 6.00 N at an angle 02 = 30.0 clockwise from the positive x direction. We use a right-handed coordinate system with the +x axis and +z axis in the horizontal plane, and the ty axis out of the page. 01 (a) Find the friction force acting on the sled if it moves with constant velocity, Express your answer in vector form. f = (131 + 6.9j) X Did you draw a diagram showing the components of the forces? What is the acceleration for an object moving with constant velocity? N (b) What is the coefficient of kinetic friction between the sled and the ground? 0.077 1X What is the relationship between friction force and normal force? (c) What is the acceleration of the sled if F1 is doubled and F2 is halved in magnitude? Express your answer in vector form. a = 0.617 X Activate Windows What is the direction of the net force now? What are the components of the friction force in this direction? m/s Go to Settings to activate Windows
