B. 24 ohms.
in parallel, combined resistance is less than the lowest resistance
Answer:
D. 4 m
Explanation:
According to the work-energy theorem, the work done by the force acting on a body modifies its kinetic energy.
The car comes to rest after a given distance, so . Recall the definition of work , here F is the constant force acting on the car, d is its traveled distance and is the angle between the force and the displacement, since friction force acts opposite to the direction of motion :
We have:
Thus:
We know that in a collision the momentum is conserved, that is:
Since this is vector equation we can divide it in two scalar equations, one for x and for y. Then we have:
Then we have for the x direction:
and for the y direction:
Hence, we have the system of equations:
From the second equation we have:
Plugging this in the first equation:
Now that we know the value of the angle we plug it in the expression for the velocity, then we have:
Therefore, the magnitude of the final speed of the orange ball is 1.04 m/s and the direction is 69.69°
