- A 10 kg box experiences a force of 15 Newtons in the positive x-direction and 8 Newtons in the negative y-direction. What is the magnitude of the net force acting on the box? Answer in Newtons.A lamp hangs vertically from a cord in a descending elevator that decelerates at 1.7 m/s2. (a) If the tension in the cord is 63 N, what is the lamp's mass? (b) What is the cord's tension when the elevator ascends with an upward acceleration of 1.7 m/s2?A man stands on a scale in an elevator that is accelerating upward. The scale reads 973.8 N. When he holds a 44.0 kg box, the scale reads 1449.8 N. What is the man's mass? and What is the magnitude of the acceleration of the elevator?
- A 15 kg box is motionless on a ramp that has a 30 degrees incline. What is the force of friction acting on the box?A box with mass 32.5 kg rests on a frozen pond, which serves as a frictionless horizontal surface. If a fisherman applies a horizontal force of 14.0N to the box causing it to accelerate to the right. What is the acceleration produced? How far does the crate travel in 10.0 seconds?When you push a 1.80-kg book on a tabletop, it takes 2.25 N to start the book sliding. Once it is sliding, however, it takes 1.50N to keep the book moving with constant speed. What are the coefficients of static and kinetic friction between the book and the table top?
- 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.
