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)(1 point)
Responses
4000 N
4000 N
1000 N
1000 N
0.001 N
0.001 N
0.5 N
The net force acting on the roller coaster can be calculated using the formula: Force = mass x acceleration.
Substituting the given values, we get: Force = 2000 kg x 2 m/s^2 = 4000 N.
Therefore, the net force acting on the roller coaster is 4000 N.
