A 2.80-kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring. a. Determine the force constant of the spring, if the box compresses the spring 5.50 cm before coming to rest. b. Determine the initial speed the box would need in order to compress the spring by 1.30 cm. A box slides from rest down a frictionless ramp inclined at 39.0° with respect to the horizontal and is stopped at the bottom of...
A box of unknown mass is sliding with an initial speed Vi= 5.70 m/s across a horizontal frictionless warehouse floor when it encounters a rough section of flooring d= 2.30 m long. The coefficient of kinetic friction between the rough section of flooring and the box is 0.100. Using energy considerations, determine the final speed of the box (in m/s) after sliding across the rough section of flooring.
A box of unknown mass is sliding with an initial speed vi = 5.00 m/s across a horizontal frictionless warehouse floor when it encounters a rough section of flooring d = 2.60 m long. The coefficient of kinetic friction between the rough section of flooring and the box is 0.100. Using energy considerations, determine the final speed of the box (in m/s) after sliding across the rough section of flooring.
A box of unknown mass is sliding with an initial speed vi = 5.80 m/s across a horizontal frictionless warehouse floor when it encounters a rough section of flooring d = 2.30 m long. The coefficient of kinetic friction between the rough section of flooring and the box is 0.100. Using energy considerations, determine the final speed of the box (in m/s) after sliding across the rough section of flooring.
A 600 N box is sliding down a ramp. I am in front of the ramp pushing uphill, so that the box slides with a constant velocity. The top of the ramp is 1.5 m above the bottom of the ramp and the ramp is 5.0 m long. As the box slides down, friction does work and 500 J are added to the thermal energy of the ramp and box. a. Calculate the work done by one external force in...
A) A massless rope is tied to a 1.82 kg box sitting on a rough, horizontal surface. The rope is pulled with constant force F acting upward at an angle 15.8o to the horizontal. The coefficient of kinetic friction between the box and the surface is 0.217, and the box slides at constant speed along the table for a distance of 84.4 m. Find the total work done by F, in J. B)Josh, mass 143 kg, is racing against his...
19) You push a 34 kg crate, accelerating from rest to a speed of 3 m/s. You use up 2000 J of your energy. How energy efficient is this process? How much thermal energy was generated by your efforts and the sliding friction acting on the crate?
19) You push a 33 kg crate, accelerating from rest to a speed of 3 m/s. You use up 3000 J of your energy. How energy efficient is this process? 20) How much thermal energy was generated by your efforts and the sliding friction acting on the crate?
A box accidentally drops from a truck traveling at a speed of 20.0 m/s and slides along the ground for a distance of 30.0m. Calculate: The acceleration of the box (assuming it is constant while sliding) The time to come to rest. The distance traveled during the first second after falling off the truck
Two boxes are sliding to the right on a horizontal frictionless surface. Box 1 is trailing box 2. Box 1 has a mass of 2 kg and a speed of 5 m/s, while box 2 has a mass of 4 kg and a speed of 3 m/s. Eventually, box 1 catches up to box 2 and experiences a completely inelastic collision with box 2. What is the speed of the two blocks after the collision?
