A1.0 kg red superball moving at 5.0 m/s collides head-on with stationary blue superball of mass 4.0 kg in an elastic collision. what are the final velocities of the two superballs after the collision?

final speed of blue ball = 2m/s

final speed of red ball = -3 m/s

Explanation:

As we know that for elastic type of collision the coefficient of elasticity is always 1 and it is given by

here we know that

now we have

also we can use the momentum conservation for this type of collision

so we will have

so we have

now from above two equations we will have

also we have

so final speed of blue ball = 2m/s

final speed of red ball = 3 m/s

its a 5.5 n

glad that

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
