A box with a mass of 20 kg is supported on a 5-meter ramp with an inclination angle of 30° relative to the horizontal plane. The box starts its descent from rest and slides without friction along the ramp until it reaches the ground. Calculate the total mechanical energy of the box when it reaches the ground.

Question 1:

Medium

João decided to conduct an experiment with a spring from his toy, attaching it to the ceiling of his house and hanging a 0.4 kg object at the end. João observed that the spring stretched 20 cm when the object was attached and wants to determine the work done by the elastic force in this situation. Knowing that the object came to rest and that the spring constant is 50 N/m, do the following: a) Calculate the elastic force exerted by the spring on the object. b) Calculate the work done by the elastic force in stretching the spring by 20 cm. c) Explain how the calculated value of the work done by the elastic force can be analyzed so that João can make predictions about the behavior of the object in future experiments.

Question 2:

Medium

In terms of Elastic Force, it is correct to state that elastic forces are the result of the movement of two particles that attract each other, thus generating elastic potential energy. Where is this elastic potential energy stored?
