Question
A block of mass M is moves down a frictionless ramp of angle θ and height H. The block is pushed at the top of the ramp so that its initial speed is 4 m/s.
Consider system A to be only the block and system B to be the block and the earth together. Is the speed of the block at the bottom of the ramp in system A ________the speed of the block at the bottom of the ramp in system B?
greater than, less than, or equal to ?

Please only use the formulas, constants, and units from the picture given. To simulate various processes on the surface on Mars, a labratory uses an Atwood machine to simulate Martian gravitational acceleration. An Atwood machine is a setup involving two objects connected by a string that runs over a pulley. For this problem, assume that the string and pulley are ideally frictionless, massless, and inextensible. One object is a bucket holding the subject of the labratory's experiment, which in total has a mass mb. The other object is a counterweight, whose mass Mc must be properly selected to ensure that the experiement's downward acceleration matches that of Martian gravity, gM. Part 1) The experimenter want the bucket to be accelerated as if it were being dropped near the surface of Mars. Which mass must be bigger, Mb (the bucket) or Mc (the counterweight)? How does the acceleration of the bucket compare…arrow_forward
