A 4 kg ball moves with a velocity of 10m/s wide with a 16kg ball moving with a velocity of 4m/s (a) calculate the velocity of ball in each case they stick together on impact and loss of energy resulting from impact (b) state the principle used to calculate the velocity of the ball.

Which articulations allow for greatest range of motion?

An object in mechanical equilibrium is an object

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.)
