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:
Formula for momentum is mass times velocity so you do 52 kg times 5 m/s and that equals 260 kg x m/s

Answer:
The recipe for a hurricane is a combination of warm, humid wind over tropical waters. The temperature of tropical waters must be at least 80 degrees F for up to 165 feet below the ocean’s surface. As this warm water meets the wind that blows west from Africa across the ocean, it causes the water to vaporize. The water vapor then rises into the atmosphere, where it cools and liquefies.
