Answer:
12J
Explanation:
Kinetic Energy before collision = 1/2mv1^2 = 1/2×2×4^2 = 16J
Velocity after collision (v2) = m1v1/m1+m2 = 2×4/2+2 = 8/4 = 2m/s
Kinetic Energy after collision = 1/2mv2^2 = 1/2×2×2^2 = 4J
Kinetic Energy lost = 16J - 4J = 12J
209 km/h = 58.0 m/s
2as = v² - u²
Assuming the ball started from rest,
a = (58)² / 2 x 0.11
a = 15,290 m/s²
Answer:
2.06 m at 49.7 or 50 degree South of East
Explanation:
take x axis and y axis and follow as explained in attachment
Answer:
the voltage across each resistor is one third of the battery voltage
Explanation:
In a series circuit, the current is constant throughout the circuit, so the battery voltage is equal to the sum of the voltage drop in each part of the series circuit.
V = i (R₁ + R₂ + R₃)
in the exercise indicate that all resistance has the same value
R₀ = R₁ = R₂ = R₃
V = i 3 R₀
V
= 3 V₀
V₀ = i R₀
V₀= V / 3
the voltage across each resistor is one third of the battery voltage
