What will be acceleration if a car changes its velocity from 10 m/s to 6 m/s in 2 seconds?

Answer»

Answer:

given DATA:

u=10 m/s

v=6 m/s

t=2 s

to CALCULATE:

acceleration,a=?

formula:

a =  \frac{v - u}{t}

calculation:

a =  \frac{v - u}{t}  \\  =  \frac{6 - 10}{2}  \\   = \frac{ - 4}{2}  \\  =  - 2

here, negative sign represents decreasing acceleration.

your answer is -2

therefore, change in acceleration of car changing VELOCITY of car from 10m/s to 6m/s in 2S is 2m/s²

hope it helps to you☺️
