Question

A jet is traveling at 100 meters per second and then accelerates at 10 meters
per second squared for 100 meters. what is it's final speed?

Answer 1

Answer:

109.6m/s

Explanation:

Given parameters:

Initial velocity  = 100m/s

Acceleration = 10m/s²

Distance  = 100m

Unknown:

Final speed  = ?

Solution:

To solve this problem, we use the expression below;

      V²  = U²  + 2aS

 V is the final velocity

 U is the initial velocity

  a is the acceleration

 S  is the distance

   V²  = 100² + 2(10)(100)

   V² = 10000 + 2000

   V² = 12000

    V = √12000 = 109.6m/s
