Question

A roller coaster begins at the top of a hill. If it accelerates at the rate of 2 m/s and has a mass of 2000 kg, what net force is acting on it? (Force=mass x acceleration). 0.001 N. 1000 N. 0.5 N. 4000 N.

To find the net force acting on the roller coaster, we can use Newton's second law of motion, which states:

\[
\text{Force} = \text{mass} \times \text{acceleration}
\]

In this case, the mass of the roller coaster is 2000 kg, and its acceleration is 2 m/s². Plugging in these values:

\[
\text{Force} = 2000 \, \text{kg} \times 2 \, \text{m/s}^2 = 4000 \, \text{N}
\]

Thus, the net force acting on the roller coaster is **4000 N**.
