Your answer is 20
just take 1,200 divided by 60 [second] :)
Answer: 25.7m/s
Explanation: the cars have equal masses so we only consider their velocities,
The cars traveled together at 65° north of east this is with a velocity equal to the resultant velocity,
Using the force diagram as shown below;
Tan 65° = Vn/Ve
Ve is velocity of the car traveling east
Vn is velocity of car traveling north
Tan 65° = V2/12
2.144 = V2/12
V2 = 12 * 2.144
V2 = 25.7 m/s
The net force on the hanging object is zero. If it were not zero, then the object would be accelerating in some direction.
It *can* be called "Dynamic Electricity".
Hope that helps a little bit XD.
