A golf player hits a 0.045 kg golf ball that is initially at rest, changing its momentum by 4.2 kg times m/., What is the final speed of the golf ball?

v₂ = 93.33 [m/s]

Explanation:

In order to solve this problem, we must apply the definition of momentum and amount of movement, which can be calculated by means of the following expression.

where:

P = momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

The amount of movement before and after the impact should be analyzed.

where:

m₁ = mass of the ball = 0.045 [kg]

v₁ = velocity of the ball before the hit = 0

Imp₁₋₂ = Impulse [kg*m/s]

v₂ = velocity after the hit [m/s]

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
