An object initially at rest experiences an acceleration of 6.2 m/s2. How much time will it take to achieve a velocity of 155 m/s?

What are the details?

• vf = 155 

  vi = 0

  a = 6.2

  t = 0

• vf = 155 m/s

  vi = 0

  a = 6.2 m/s2

  t = ?

• vf = ? 

  vi = 6.2 m/s2

  a = 155 m/s

  t = ?

An object is moving at a velocity of 14 m/s. It accelerates to a velocity of 48 m/s over a time of 10 s. What acceleration did it experience?

Which equation should you use to solve?

• a = vi - vf * t

• a = (vf - vi) / t

• vf = vi + a * t

• a = vf + vi * a
