If A 0.50 kg ball with a speed of 4.0 strikees a stationary 1.0 kg target if momentum is conserved what is the total momentum of the ball and target after te collision?

Answer 1

When the 0.500kg ball collides with the stationary ball, momentum is conserved.

Meaning, initial momentum = final momentum.

Momentum of an object is = mass(m) x velocity (v).

If two objects are in the system, then you have to add up both initial momentums and set them equal to the final momentums...

So...

m x v(initial, first object) + m x v(initial, second object) = final momentum.

(0.500kg)(4.0m/s) + (1.0kg)(0m/s) = final momentum.

So the final momentum equals 2.0kgm/s...

D. 2.0 kgm/s
