an automobile manufacturer claims that its product will travel 0.5 km in 22 s, starting from rest. What is the magnitude of the constant acceleration required to do this?

Respuesta :

Answer:

The magnitude of the constant acceleration required to do this is 2.07 m/s²

Explanation:

Given;

distance the automobile will travel, d = 0.5 km = 500 m

initial velocity of the automobile, u = 0

time of travel, t = 22 s

Apply the following kinematic equation to determine the constant acceleration;

d = ut + ¹/₂at²

500 = 0 + ¹/₂(22)²a

500 = 242a

a = 500 / 242

a = 2.07 m/s²

Therefore, the magnitude of the constant acceleration required to do this is 2.07 m/s²
