The mass of a basketball is three times greater than the mass of a softball. Compare the momentums of a softball and a basketbal
ki77a [65]

Answer:

The momentum of the basketball is three times that of the softball. Momentum equals mass times velocity. Therefore, if the basketball and softball are moving at the same velocity, and the basketball has three times the mass of the softball, the basketball has three times the momentum of the softball.

A ball of mass 0.440 kg moving east (+x direction) with a speed of 3.80 m/s collides head-on with a 0.220-kg ball at rest. If th
avanturin [10]

Answer:

The speed and direction of each ball after the collision is  1.27 m/s to East direction and  5.07 m/s to East direction.

Explanation:

given information

m₁ = 0.440 kg

v₁ = 3.80 m/s

m₂ = 0.220 kg

v₂ = 0

collision is perfectly elastic

v₁ - v₂ = - (v₁'- v₂')

v₁ =  - (v₁'- v₂')

v₂' = v₁ + v₁'

according to momentum conservation energy

m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'

m₁v₁  = m₁v₁' + m₂(v₁ + v₁')

m₁v₁  =  m₁v₁' + m₂v₁ + m₂v₁'

m₁v₁ - m₂v₁ = m₁v₁' + m₂v₁'

v₁ (m₁ - m₂) = (m₁ + m₂) v₁'

v₁' = (m₁ - m₂)v₁ / (m₁ + m₂)

    = (0.440 - 0.220) (3.8) / (0.440 + 0.220)

     = 1.27 m/s to East direction

v₂' = v₁ + v₁'

    = 3.8 + 1.27

= 5.07 m/s to East direction

Will the centripetal force on the bob be different on the moon
ivanzaharov [21]
Hello
I think some details of the question are missing. However, I believe you are referring to a bob following some circular path. Therefore, the answer is "no": in fact, the centripetal force is equal on the earth and on the moon. 

Keep in mind that the centripetal force is given by
F=m \frac{v^2}{r}
where m is the mass, v the tangential velocity and r the radius of the circular motion. The mass m of the bob is the same on the earth and on the moon, so the centripetal force is the same.
