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

109.6m/s

Step-by-step 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
