Answer:
78 N s
Explanation:
The impulse exerted on the ball is given by:

where
F is the magnitude of the force
is the duration of the collision
In this problem,
F = 39 N

Substituting,

Answer:
Another danger that comes with intrapreneurs is the lack of patience from other people in the office. To people who have worked their whole lives in one company, they might expect to see instant results from somebody who has waltzed in and promised big things.
To solve this problem it is necessary to apply the concepts related to Ohm's Law to find the voltage in the case of direct current. While for the Alternate current we use the concept of RMS voltage.
PART A) In the case of DC we have to,
V=IR
Where,
I = Current
R = Resistance
Where the current is 60mA y the resistance is
, then the potential would be


In the case of DC we have that the current and the RMS voltage is,



The potential in AC then is,



Average acceleration = (change in speed) / (time for the change)
In this case . . .
Average acceleration = (speed at the end - speed at the beginning)/10sec.
We can't be any more specific without knowing the difference
between the beginning speed and the ending speed.
