Troyanec [42]

Impulse = Change in momentum.  
The ball was moving with a momentum of 0.45 * 22 = 9.9  
The ball comes to rest in the receivers arm; this means the ball's final velocity = 0. So mv2 = 0.45 * 0  
The magnitude of the impact is just the change in momentum. 9.9 - (0.45 * 0) = 9.9

Change into60f into c​
Reil [10]

Answer:

15.6 C

Explanation:

Here we are given a temperature in Fahrenheit (F). We want to convert it into Celsius degrees (C).

The conversion can be done by using the following equation:

T(C)=\frac{5}{9}(T(F)-32)

where

T(C) is the temperature in Celsius degrees

T(F) is the temperature in Fahrenheit degrees

In this problem, we have

T(F) = 60 F

Therefore, by applying the equation,

T(C)=\frac{5}{9}(60-32)=15.6 C
