What is the equation for finding the acceleration of an object moving in a straight line?
1 answer:
The equations to find the acceleration are the suvat equations:
Explanation:
The acceleration of an object is the rate if change in velocity of the object. It is calculated as
where
v is the final velocity of the object
u is the initial velocity
t is the time elapsed
For an object moving in a straight line at constant acceleration, there are several equations that can be used to find the acceleration: they are called suvat equations. They are the following:
where
u is the initial velocity
v is the final velocity
t is the time
s is the distance covered
a is the acceleration
Therefore, any of the above equations can be used to calculate the acceleration.

Remember what acceleration is? It's how fast the speed is changing over a period of time.
So in dt = 2 secs, she sped up from 6 to 10 m/s and so dv = (10-6) m/s.
Now that you know dv and dt, you can calculate the acceleration a!
So in dt = 2 secs, she sped up from 6 to 10 m/s and so dv = (10-6) m/s.
Now that you know dv and dt, you can calculate the acceleration a!
Answer
given,
initial speed of the car = 90 m/s
final speed of the car = 0 m/s
distance taken to stop = 110 m
calculating the acceleration of the car = ?
using the equation of motion
v² - u² = 2 a s
0² - 90² = 2 x a x 100
a = 40.5 m/s²
acceleration of the formula one car is equal to a = 40.5 m/s²
