A car with a mass of 2700 kg is rolling down a hill with a grade that is 15° above the horizontal with a velocity of 2 m/s. The car had 400m before it hits the water barrels which act as springs. A. Calculate the total energy the car has at the top of the hill

B. At the bottom of the hill, the car smashed into water barrels which act as spring with a spring constant of 1,500,000 N/m. How much distance will the water barrel/spring need to compress to stop the car?

C. If the water barrels are only 1.5m thick, will the car come to a complete stop. Explain your reasoning.

*at least find the height and answers C*

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
