Consider a hypothetical icy planet with a mass of 1.56 x 102 kg and a radius of 2.36 x 10 m. A 255 kg robot falls toward the surface from a height that is negligible compared to the radius of the planet. V Part A Draw a free-body diagram for the force(s) acting on the robot. Note that there are more possible vectors listed than belong in the free-body diagram. + No elements selected Select the elements from the list and add them to the canvas setting the appropriate attributes.Part B What is the acceleration due to gravity on this hypothetical planet? ? a m/ $2 Submit Request Answer Part C Let's suppose we send the robot sledding on this hypothetical planet. The robot and sled are launched from rest from the top of an 8.50 m hill by a spring. This spring has a spring constant of 1255 N/m, the robot and sled compress the spring 1.65 m before launching, and the mass of the robot and sled is 255 kg, assuming the mass of the sled is negligible compared to that of the robot. What is the total mechanical energy of the robot and sled at the top of the hill? AEd ? Etop = Submit Request Answer Part D What is the speed of the sled and robot at the bottom of the frictionless 8.50 m hill? AEd 0 8 ! ? Ubot = m/s Submit Request AnswerPart E At the bottom of the hill, the robot and sled continue to slide along the rough ground until friction causes them to stop. What is the magnitude of the friction force that causes the robot and sled to stop if they travel a distance of 22.8 m before stopping? AEd ? Ff= N Submit Request Answer Part F How long does it take the robot and sled to stop? ? t = Submit Request
