Two objects of the same mass are on two different planets. planet a has a force of gravity that is weaker than that of planet b. how will the weights of the objects compare to each other? the weights of the objects will be the same. the weight of the object on planet a will be greater than the weight of the object on planet b. the weight of the object on planet a will be less than the weight of the object on planet b. this cannot be determined without knowing the actual mass of the objects.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
