Marissa designs a robot that goes on a mission to mars. the acceleration of gravity on mars is 3.7 m/s^2. the robot has a mass of 18 kg.

a. how does the mass of the robot change once it gets to mars? explain

b. how does the weight of the robot change once it gets to mars? explain

The slope of a velocity time graph over any interval of time gives the during that interval

Abox is sliding on a frictionless surface when it suddenly begins to rain heavily. if the downpour of rainfall falls vertically into the box

You want to move a heavy box with mass 30.0 kg across a carpeted floor. you pull hard on one of the edges of the box at an angle 30∘ above the horizontal with a force of magnitude 240 n, causing the box to move horizontally. the force of friction between the moving box and the floor has magnitude 41.5 n . what is the box's acceleration just after it begins to move
