Block A has a mass of 2kg and a speed of 50 m/s along the positive x axis. Block B has a mass of 4 kg and a speed of 25 m/s along the negative x axis.

The two blocks collide head-on in a perfectly elastic collision.

Determine the velocity of each mass after the collision.

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
