Determine the magnitude of acceleration of his car and his distance traveled.

Question

Please Help me answer this Problem.

Adrian Guerrero accelerates his race car uniformly from 18.2 m/s to 48.2 m/s in 2.45 s. Determine the magnitude of acceleration of his car and his distance traveled.

Answer 1

First, we need the definition of acceleration.

 

acceleration = ( V_final - V_initial ) / time

 

Now we plug in what was given to us.

 

( 48.2 - 18.2 ) / 2.45

 

and we find that the acceleration is 12.2 m/s²

 

To find the distance traveled, we should use the V² formula

 

v_f² = vi² + 2 * a * distance

 

48.2² = 18.2² + 2 * 2.45 * distance

 

Solve for distance for the final answer.
