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
In a constant acceleration of 3m per second, after 10 seconds,
3 x 10 = 30
B. 30m/s is your answer
hope this helps XD
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:

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,
