Answer fast . the bottom of a box has a surface area of 25.0 cm 2 . the mass of the box is 34.0 kilograms. acceleration due to gravity at sea level is 9.80 m/s 2 . what pressure is exerted by the box where it rests? a. 1.36 n/cm 2 b. 13.3 n/cm 2 c. 0.139 n/cm 2 d. 7.21 n/cm 2

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
