1.06 m
Explanation:
The kinetic friction of the grass on the sled is the product of friction coefficient and the normal force, which equals to gravitational force. Let g = 9.81 m/s2:
So the deceleration caused by kinetic friction on the 60 kg sled is
If the sled on a speed of 2.5m/s and then subjected to a deceleration of 2.943 m/s2, then we can use the following equation of motion to find out the distance traveled by the sled before rest:
where v = 0 m/s is the final velocity of the sled when it stops, = 2.5m/s is the initial velocity of the can when it hits, a = -2.943 m/s2 is the deceleration, and
is the distance traveled, which we care looking for:
Answer:
Since we have identical diodes we can use the equation:
And replacing we have:
Since we know that 1 mA is drawn away from the output then the real value for I would be
And for this case the value for would be:
And the output votage on this case would be:
And the net change in the output voltage would be:
Explanation:
For this case we have the figure attached illustrating the problem
We know that the equation for the current in a diode id given by:
For this case the voltage across the 3 diode in series needs to be 2 V, and we can find the voltage on each diode and each voltage is the same v for each diode, so then:
Since we have identical diodes we can use the equation:
And replacing we have:
Since we know that 1 mA is drawn away from the output then the real value for I would be
And for this case the value for would be:
And the output votage on this case would be:
And the net change in the output voltage would be:
