Question

A baseball has a mass of 140 grams and a softball has a mass of 280 grams. In which of the following situations would they both have the same momentum? A) The baseball and softball are thrown at 33 m/s in the same direction. B) The baseball and softball are thrown at 33 m/s in opposite directions. C) The baseball is thrown at 50 m/s and the softball is thrown at 25 m/s. D) The baseball is thrown at 25 m/s and the softball is thrown at 50 m/s.

Answer 1

Answer:

 (D) The baseball is thrown at 25 m/s and the softball is thrown at 50 m/s.

pls mark as brainliest answer

Explanation:

Answer 2

Answer:

D.) The baseball is thrown at 50 m/s and the softball is thrown at 25 m/s.

Explanation:

mass of ball 1

m_1 = 140 grams

mass of ball 2

m_2 = 280 grams

now we know that if the momentum of two balls are same then we will have

P_1 = P_2

m_1v_1 = m_2 v_2

so we have

140 v_1 = 280 v_2

v_1 = 2 v_2

so velocity of light ball must be twice the velocity of heavy ball

so correct answer will be

D.) The baseball is thrown at 50 m/s and the softball is thrown at 25 m/s.
