a roller coaster begins at the top of a hill if it acelerates at the rate of 2 m/s2 and has a mass of 2000 kg what net force is acting on it

Explanation:

Force can be found by multiplying the mass by the acceleration.

The mass of the roller coaster is 2000 kilograms and the acceleration is 2 meters per second squared.

Substitute the values into the formula.

Multiply.

The net force acting on the roller coaster is 4000 Newtons.

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

0.19 m/s and 0.45 m/s
