Question

Please help correct answering get 20 points (physical science btw )

A roller coaster goes down a slope with a starting speed of 5 m/s then 6
seconds later at the bottom of the slope the roller coaster is moving at a
speed of 27 m/s. What is the acceleration of the roller coaster? **Round to
1 decimal place**

Answer 1

Acceleration = 3.67 m/s²

Step-by-step explanation:

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

`Acceleration (a) = (final \; velocity - initial \; velocity)/(time)`

Given the following data;

Initial velocity, u = 5 m/s

Final velocity, v = 27

Time, t = 6

To find the acceleration;

Acceleration = (v - u)/t

Acceleration = (27 - 5)/6

Acceleration = 22/6

Acceleration = 3.67 m/s²
