Use einstein’s energy equation to solve the following problem. recall that the speed of light is 3 × 108 m/s. if a 5.0-kg stone is completely converted to energy, what is its energy equivalent in joules?

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
