Hello, I was given the hw question that wanted to know if a basketball player is getting ready to jump, pushing off the ground and accelerating upward, what are the forces acting on the player? I have tried the options many of times but can't figure out where I am wrong. For the most part it can't be too many forces acting on the player.  The multi-choice options were: Weight Tension Force Kinetic Friction Force Normal Force I have chosed Normal Force and Weight as my top two. But somehow i'm still wrong or missing something.

Two ropes apply a force to a boat. The first is 200 N in the positive x direction, and the second is 250 N in the positive y direction. At what angle must a third rope tension be applied in order to keep the boat at rest? Your Answer:

What is the acceleration of the two object?A horizontal cord is attached to a 15kg body on a horizontal tabletop. The cord passes over a pulley at the end of the table edge. At the end of this cord is a body of mass 20kg.

A 40 N box is resting on a table when a 20 N force is applied to it horizontally. The coefficients of static and kinetic friction are 0.3 and 0.1, respectively. Which of the following best describes the resulting motion of the box?    The motion of the box cannot be determined with the given information.      The box accelerates in the direction of the applied force.      The box remains at rest.      The box moves with a constant velocity in the direction of the applied force.

Joe pushes down the length of the handle of a 14.1 kg lawn spreader. The handle makes an angle of 47.1° with the horizontal. Joe wishes to accelerate the spreader from rest to 1.39 m/s in 1.7 s. What force must Joe apply to the handle? Answer in units of N.

A box of mass ?=24.5 kg is pulled up a ramp that is inclined at an angle ?=19.0∘ angle with respect to the horizontal. The coefficient of kinetic friction between the box and the ramp is ?k=0.345 , and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of ?=2.09 m/s2, calculate the tension ?T in the rope. Use ?=9.81 m/s2 for the acceleration due to gravity.

You have to push a cart (which has a mass of 11 kg) to the top of a hill, which has a steady incline of 33° above the horizontal. You apply a force of 95 N (walking up the hill and pushing in a direction parallel to the incline) and push the cart at constant speed. a) What is the normal force acting on cart while it is being pushed up the hill? b) What is the force of kinetic friction acting on the case of popcorn while it is being pushed up the hill? c) What is the net force acting on the case of popcom while it is being pushed up the hill?

A box is placed on a rough floor. When you push horizontally against the box with a 40N force, the box just begins to slide. What is the magnitude of the friction force when you push against the box with a 25 N force? O58 N O 15 N O 40 N 98 N O none of the answers O 25 N

The forces act on a 1.8 kg object what is the value of ax, the x component of the object's acceleration (express answer with appropriate units) what is the value of ay , the y component of the object's acceleration (express answer with appropriate units)
