Answer:
acceleration is 1.6 m/s^2
Step-by-step explanation:
This is a question involving Kinematics so we can use one of the kinematic equations.
Given info: Vi= 2.6 m/s. Vf= 15.4 m/s. T= 8s
We need to solve for acceleration
The best equation to use is (Vf = Vi + at) as it contains all the info we need to solve for acceleration.
Now substitute the values given into the equation.
Vf = Vi + at >> 15.4 = 2.6 + a8
Now solve for a by rearranging the equation.
15.4 -2.6= 8a >> 12.8=8a >> 12.8/8= 8a/8 >> 1.6 =a
NOTES:
Acceleration is the rate of increase of velocity
Vf is final velocity or velocity after acceleration/de-accaeleration occurs
Vi is intial velocity or velocity before acceleration or de-accaeleration occurs
Time is time it took for a certain motion to occur.
