Constants Any event can be considered from different perspectives. In particular, the description of the motion of a given object would depend on the motion of the person describing the motion, the observer. Any such observer, equipped with a coordinate system anda stopwatch, forms a trame of reterence. Usually, we assume that a trame of reterence is attached to some object. For instance, "the trame of reterence of earth" means the observer is at rest relative to earth. In this...

7.7. Please answer all the
questions and show your work.
A 4.20-kg block is set into motion up an inclined plane with an initial speed of v_1 = 7.60 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of theta = 30.0 degree to the horizontal. For this motion, determine the change in the block's kinetic energy. J For this motion, determine the change in...
