A woman, driving a golf ball off of the tree, gives the ball a speed of 20.0m/s. The mass of the ball is 45g and the duration of the impact with the golf club is 6.0x10^3 a) What is the change in the momentum of the ball?

b) Determine the average force applied by the club.

Shania is trying to determine the oldest geologic unit on this map and the reason to why is she unable to do so is that the units are all the same age.. when there is the same age, there will be no oldest geologic unit and that i cannot be credible.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)

explanation:

See the answers below.

Explanation:

a)

The change in momentum can be calculated by means of the following equation.

[tex]P=m*v[/tex]

where:

P = momentum [kg*m/s]

m = mass = 45 [g] = 0.045 [kg]

v = velocity = 20 [m/s]

[tex]P=20*0.045\\P=0.9[kg*m/s][/tex]

b)

The change in momentum can also be calculated by means of the product of force by the duration time of the impact.

[tex]F*t=P\\F*0.006=0.9\\F=0.9/0.006\\F =150 [N][/tex]
