Question

A person walking with a stroller at a rate of 1.5 m/s accelerates at a rate of 0.275 m/s2.

What is the velocity (in m/s) of the stroller after is has traveled 6.45 m?

Answer 1

2.41m/s

Step-by-step explanation:

Given parameters:

Initial velocity = 1.5m/s

Acceleration = 0.275m/s²

Distance = 6.45m

Unknown:

Final velocity = ?

Solution:

To solve this problem, we apply the kinematics equation below:

v² = u² + 2aS

v is the final velocity

u is the initial velocity

a is the acceleration

S is the distance

v² = 1.5² + (2 x 0.275 x 6.45)

v = 2.41m/s
