How do we reorder the acceleration equation to solve for final speed?

V2 = V1 + (a x t)
200
A _____________ _____________ is a place or object used for comparison to determine if something is in motion.
What is reference point

A car accelerates at a rate of 3.0 m/s2. If its original speed is 8.0 m/s, how many seconds will it take the car to reach a final speed of 25.0 m/s?

5.7 seconds

Don't forget!  t = (v2 - v1) / a

To calculate _______________ ________ divide the total distance traveled by the total time.
What is average speed.
300
If you know a car travels 30 km in 20 minutes westward, you can find its _______.
What is velocity.
300
Acceleration refers to __________ ______, __________ _________, or __________.

While traveling along a highway, a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration?

a = (v2 - v1) / t

a = (15 - 24) / 12

a = -9 / 12

a = -0.75 m/s2

400
Both _________ and _________ include the direction of an object's motion.
What is speed and acceleration.
400

Convert 118 cm to meters

What is 1.18 meters

500

The distance the object moves per unit of time?

What is speed

500

What is the equation for acceleration?

A = v2 - v1 / time

A helicopter’s speed increases from 35 m/s to 60 m/s in 5 seconds. What is the acceleration of this helicopter?

a = (v2 - v1) / t

a = 60 - 35 / 5

a = 25 / 5

a = 5 m/s2
