A train accelerates at a rate of 4.5 meters/s squared. If it starts its acceleration at 15 m/s how far has it gone after 10 seconds?

Respuesta :

Answer:

60m/s

Explanation:

Given acceleration,  and time of acceleration, the problem is as simple as placing your givens into the proper kinematics equation:

[tex]v_{f} =v_{o} +a t[/tex]  

plug in your numbers and:

[tex]v_{f} =(15)+(4.5)(10)[/tex]

[tex]v_{f} =60 m/s[/tex]
