The frictionless system is tested on Mars (g=3.71m/s^2). On earth, when m=15.0kg and allowed to fall 5.00m, it gives 250.0J of KE to the drum. How far would the mass have to fall on Mars to impart the same KE?

2. -/1 pointsserpse10 2.7.p.017.mi. an object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x direction when its x coordinate is 2.97 cm. if its x coordinate 2.85 s later is -5.00 cm, what is its acceleration? cm/s2 need ? read it master it
