How can i calculate velocity when given time and distance measurements?
i'm trying to get the average velocity of these : i don't necessarily need anyone to do the work, i more so need the formula and a simple demonstration !
distance (m)
average time (s)
0.5
0.5
1.0
2.1
1.5
3.3
2.0
5.5

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.)
