Problem:
Levi started from rest along a straight path. After 3 seconds from rest, his speed was 5.0 m/s. After 10 seconds from rest, his speed was 26.0 m/s. What was his acceleration during the time 3 seconds to 10 seconds? (Show your solutions.)
Given Problem:
Vi ( initial velocity ) = 5.0 m/s
Vf ( finial velocty ) = 26.0 m/s
t ( time ) = 7 s
a ( acceleration ) = ? unknown
Solution:
We can use the formula ( a = Vf -Vi / t ) in order to solve the given Problem
a = Vf -Vi / t
= 26.0 m/s - 5.0 m/s / 7 s
= 21 m/s / 7 s
= 3 m/s²
Answer:
The acceleration is equal to 3 m/s²
