Iwill give out a if i were to change the height of the ramp multiple times then the distance the cup moves will changethis is my hypothesis for a potential energy/ kinetic energy assignment. i had to get a cup with a hole, a ruler, a wooden block, and marble, and try to change the distance the cup moved. i really need , would out a ton if i can get answers, !

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k
