A student applies a force of 50 N to a 5 kg cart that is initially at rest on a flat, horizontal surface. Knowing that the static friction between the cart and the surface is 20 N, determine: 1) What is the work done by the force applied by the student in moving the cart a distance of 10 m? 2) What is the final velocity of the cart after traveling these 10 meters? 3) What was the energy dissipated by friction during the 10 m journey?Answer sheet:

An electric car was developed to be a more sustainable alternative to combustion cars, which use non-renewable resources. This car travels in a straight line, starting from an initial position of 20 meters and reaching a final position of 120 meters. Calculate the position variation (Δx) of this car during the journey.
