Hi there!
a.
The equation for centripetal acceleration is as follows:
Plug in the given values to solve:
b.
According to Newton's Second Law:
The acceleration is v²/r, so the net force is:
Multiply by the given mass:
c.
There is NO net force in the vertical direction since the object is NOT accelerating in the vertical direction (normal force and weight cancel).
Thus, the ONLY net force experienced by the object is in the horizontal direction and is EQUAL to the centripetal force.
#1
As per kinematics we know that
here we know that
now we will have
Now by Newton's II law
#2
part a)
Impulse = change in momentum
given that
m = 0.153 kg
v = 25.7 m/s
now we have
Part b)
As per Newton's II law we know that
as we know that
Answer:
Voltage across 33 ohm resistor is 33.886 volt
Explanation:
We have given that there is RL circuit which contain two resistance and inductance
Resistance of two resistor
So equivalent resistance
Inductance of inductive reactance
So equivalent inductive reactance
Now equivalent impedance
Voltage is given as
So current
So voltage across 33 ohm resistor
