Question

A vehicle that starts to move from rest gets an acceleration of 5m/s² within 2 seconds. Calculate the velocity and distance covered by the vehicle within the given time. [Answer: 10m/s, 10m]​

Answer 1

Answer:

V = 10m/s for the final velocity.

S = 10m for distance II.

Explanation:

Given the given information:

5m/s2 acceleration

2 seconds Equals time

Because the vehicle begins at rest, its initial velocity is 0m/s.

The first equation of motion would be used to get the ultimate velocity.

V = U + at

We have by substituting into the equation

V = 0 + 5*2

V = 0 + 10

V = 10m/s.

Now, to find the distance covered, we would use the second equation of motion.

S = ut + ½at²

S = 0*2 + ½*5*2²

S = ½*5*4

S = 20/2

S = 10m
