- A person pulls a crate 49.4 meters along a horizontal floor by a constant force 103.2 N, which acts at 37.5 degrees. The floor is rough and exerts a friction force 50 N. What is the total net work done on the crate?A coin slides over a frictionless plane and across an xy coordinate system from the origin to a point with xy coordinates (3.70 m, 4.78 m) while a constant force acts on it. The force has magnitude 2.08 N and is directed at a counterclockwise angle of 100° from the positive direction of the x axis. How much work is done by the force on the coin during the displacement?Total work with vectors
- A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a nonconservative force) acts on her. The student has a mass of 81 kg, and the height of the water slide is 11.8 m. If the kinetic frictional force does -5.1 × 103 J of work, how fast is the student going at the bottom of the slide?i need help with these two questions!A bicyclist rides 1.90 km due east, while the resistive force from the air has a magnitude of 7.13 N and points due west. The rider then turns around and rides 1.90 km due west, back to her starting point. The resistive force from the air on the return trip has a magnitude of 7.13 N and points due east. Find the work done by the resistive force during the round trip. Number Units
