From the question we are told that
The voltage is
The first resistance is
The second resistance is
Since the resistors are connected in series their equivalent resistance is
Substituting values
Since the resistance are connected in serie the current passing through the circuit is the same current passing through which is mathematically evaluated as
Substituting values
Answer:
Total momentum of the system is 378 kg-m/s
Explanation:
It is given that,
Mass of first bumper car, m₁ = 222 kg
Velocity of first bumper car, v₁ = 3.10 m/s (in right)
Mass of other bumper car, m₂ = 165 kg
Velocity of second bumper car, v₂ = -1.88 m/s (in left)
Momentum of the system is given by the product of its mass and velocity. So, the total momentum of this system is given by :
p = 378 kg-m/s
Hence, the total momentum of the system is 378 kg-m/s
