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
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.
