Question

A car increases its velocity from 7.8 m/s to 11.4 m/s with constant

acceleration. The average velocity of the car is m/s. (Round to

nearest tenth digit.)

Answer 1

The Average velocity is 10m/s

Step-by-step explanation:

step one:

The average velocity is equal to the summation of all velocities divided by the number of velocities

step two:

since we have two velocities in the question

v1=7.8m/s

v2=11.4m/s

step three:

average velocity is = (v1+v2)/2

Average velocity= (7.8+11.4)/2

Average velocity= 19.2/2

Average velocity= 9.6m/s

step four:

now we have to round the answer to the nearest tenth which is

10m/s
