A boy wants to push an empty shopping cart in a supermarket for a distance of 50 meters with a constant horizontal force of 20 N. The boy applies the force in the direction of displacement. a) Calculate the work done by the force applied by the boy on the cart to cover the mentioned distance. b) If the boy decides to apply the force at an angle of 30° above the horizontal, determine the work done by the applied force. c) Compare the results and explain the difference between the two cases.

Answer:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur id consequat justo. Cras pellentesque urna ante, eget gravida quam pretium ut. Praesent aliquam nibh faucibus ligula placerat, eget pulvinar velit gravida. Nam sollicitudin pretium elit a feugiat. Vestibulum pharetra, sem quis tempor volutpat, magna diam tincidunt enim, in ullamcorper tellus nibh vitae turpis. In egestas convallis ultrices.

A student is helping his family carry a box of 50 kg of mass to the second floor of his house. When reaching the second floor, the box was lifted to a height of 5 meters relative to the starting point. Consider that the force applied by the student is vertical and constant along the way. (a) Calculate the force that the student exerts on the box to lift it. (b) Determine the work done by the student in the task. (c) If the student takes 30 seconds to climb the stairs, what will be the average power developed during the process?

A mechanic is using a wrench to tighten the screws on a car wheel. The wrench is 0.5 meters long and the mechanic applies a force of 100N at the end of the wrench, perpendicular to its length. (a) Calculate the torque applied to the nut by the action of the wrench. (b) If the mechanic needs to apply a greater torque to loosen the nut, he can increase the force or increase the length of the wrench. Which of the two increases will be more effective? (c) To loosen the nut, the mechanic decided to use a wrench with a length of 0.75 meters and apply a force of 90N. Determine the torque applied with the new wrench.
