Jason is pulling a box across the room. He is pulling with a force of 24 newtons and his arm is making a 63 angle with the horizontal, if the box weighs 23 newtons what is the net force on the box in the vertical direction? Treat up as the positive direction, and down as the negative direction. Answer value

Multiple part question: A worker in a factory slides a heavy box up a ramp into a truck. The box has a mass of 84 kg, and the ramp is 3 m long and makes an angle of 34° with the horizontal. The coefficient of friction between the box and ramp is 0.6. What is the weight of the box? What is the normal force acting on the box? What is the force of friction acting on the box?   Assuming the worker pushes the box up the ramp with a constant velocity, how much work does the factory worker do on the box in order to get it into the truck?   How much gravitational potential energy does the box have once it reaches the top of the ramp?

Question 2 To give a 22-kg child a ride, two teenagers pull on a 3.5- kg sled with ropes, as indicated in the figure (Figure 1). Both teenagers pull with a force of 55 N at an angle of 35° relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57 N. You may want to review (Pages 134 - 136) .
