Two 0.20-kg balls, moving at 4 m/s east, strike a wall. Ball A bounces backwards at the same speed. Ball B stops. Which statement correctly describes the change in momentum of the two balls? a. |ΔpBl<|ΔPA|
b. |ΔpBl=|ΔPA|
c. |ΔpB|>|ΔPA|
d. ΔpB > ΔPA

Option A

Explanation:

From the question we are told that:

Mass

Velocity

Generally the equation for momentum for Ball A is mathematically given by

Initial Momentum

Final Momentum

Therefore

Generally the equation for momentum for Ball B is mathematically given by

Initial Momentum

Final Momentum

Therefore

Option A

atomic = no of protons.

mass number-atomic number = neutron number

i would say the answer is food.

hope this !
