The voltage in the resistor is 63 V
Explanation:
We can solve the problem by applying Ohm's law, which states the relationship between voltage, current and resistance in a resistor:
where
V is the voltage
R is the resistance
I is the current
For the resistor in this problem, we have:
I = 0.42 A is the current
is the resistance
Substituting into the equation, we find the voltage needed:

Answer:
F=4040.81 N
Explanation:
Given that
Time ,t= 2.45 ms
Mass ,m= 0.055 kg
v= 1.8 x 10² m/s = 180 m/s
We know that rate of change in the linear momentum is known as force.
Momentum P = m v
Therefore force F
F=4040.81 N
Therefore force on the ball will be 4040.81 N
