- 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 valueA student pushes a 20kg desk across the floor to the right with a force of 400 N. The coefficient of kinetic friction between the floor and the desk is equal to 0.21. Calculate the acceleration of the desk.A skier is standing on a 30o hill. Draw the hill and add idealized force vectors that represent the force of the skier (FS), the normal force (FN), and the force of friction (FF).
- A woman exerts a horizontal force of 145 N on a box with a mass of 37.2 kg If the box doesn't move, what's the magnitude of the static friction force (in N)?A 1,380-N crate is being pushed across a level floor at a constant speed by a force F of 320 N at an angle of 20.0° below the horizontal, as shown in the figure a below. a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.)(b) If the 320-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in the figure b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a).m/s2A man pulls a cement block with a force of 450N using a rope that makes an angle of 35.0 degrees above the horizontal.

Round your answer to 1 decimal place.What is the frictional force acting at A? answer in N using 3 significant digits. What is the frictional force acting at B? answer in N using 3 significant digits.Four forces act on an object, given by A = 38.3 N east, B = 45.3 N north, C = 70.7 N west, and D = 88.7 N south. (Assume east and north are directed along the +x-axis and +y-axis, respectively.) (a) What is the magnitude of the net force (in N) on the object? (b) What is the direction of the force?

- Two people play tug of war. The 100-kg person on the left pulls with 1100 N, and the 75-kg person on the right pulls with 870 N. Assume that neither person releases their grip on the rope with either hand at any time, assume that the rope is always taut, and assume that the rope does not stretch. What is the magnitude of the tension in the rope in Newtons? Add your answerA horizontal force F pushes against a block of mass m. The mass m in turn pushes against a bigger block of mass M. There isn't friction any between the larger block and the table, but there is friction in between the blocks (coef. of static friction is μs). What's the smallest force F that will hold the smaller mass m m against the larger mass M without letting the smaller mass m fall down?Answer must be in scientific notation with SI units that do not have prefixes except for kg. (m/s NOT cm/s). Answer must be in Standard Form Scientific Notation
