To find the deceleration of the roller coaster, we first need to find the acceleration between the two points.
We can use the equation:
Acceleration = (final velocity - initial velocity) / time
Acceleration = (10m/s - 25m/s) / 3s
Acceleration = -15m/s / 3s
Acceleration = -5m/s^2
The negative sign indicates that the roller coaster is decelerating.
Therefore, the deceleration of the roller coaster is 5m/s^2.
A roller coaster is moving at 25m / s at the bottom of a hill. Three seconds later it reaches the top of the next hill, moving at 10m / s What is the deceleration of the roller coaster? 24
