If the object starts from rest, find the final velocity after 3 seconds.

Question

                                                                     Newton's Second Law

 

Hello...

I found the F=6 to the left, Mass=3 and Acceleration is 2 to the left.

Question: If the object starts from the rest, find the final velocity after 3seconds.

 

 

 

Thank you for your time, Sir!

Answer 1

v(t) = at + v₀

• v(t) = velocity at time t
• a = acceleration = 2 m/s²  (assuming SI units)
• t = time  = 3 seconds
• v₀ = starting velocity = "at rest" = 0

 

Plug the numbers into the formula to get the answer. Units are m/s.
