Question

Little Tammy lines up to tackle Jackson to (unsuccessfully) prove the law of conservation of momentum. Tammy’s mass is 34.0 kg and Jackson’s is 54.0 kg. Jackson is running at a velocity of 3.0 m/s. What must Tammy’s minimum velocity be in order to stop Jackson’s forward momentum?

Answer 1

Answer:

law of conservation of momentum: mass of Tammy × velocity =mass of Jackson × velocity

Explanation:

so 34.0 kg ×v = 54.0 kg ×3.0 m/s

34.0 kg v = 162= v= 162/34

Answer 2

Answer:

4.764 m/s

Explanation:

Conservation of momentum =

m1u1 = m2u2

m1 = Mass of Jackson = 54 kg

u1 = Velocity of Jackson = 3 m/s

m2 = Mass of Tammy = 34 kg

u2 = Velocity of Tammy = Find

=> 54 * 3 = 34 * u2

=> 162 = 34u2

=> 162/34 = u2

=> u2 = 4.764 m/s
