Apolice crime lab is trying to determine whether someone was murdered or died as a result of an accident. he was struck in the temple by a 4.20 kg sculpture that is alleged to have fallen off a bookcase. the sculpture presumably fell a distance of 1.43 m and the corner that struck him had an area of 0.250 cm 2. if the time for the sculpture to stop was 1.00 ms, the pressure on his temple, in n/m 2, was

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

nah.   i'm just sleepy.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
