Question

If a Vehicle starts from rest attain uniform velocity 20m/s in 5 seconds Calculate
Its acceleration.​

Answer 1

Given

A vehicle starts from rest and attains a uniform velocity of 20 m/s in 5 seconds

To Find

Acceleration

Solution

We know that

$a = \frac{v - u}{t} \: m |s {}^{2}$

Here

• a = Acceleration
• u = Initial velocity
• v = Final velocity
• t = Time

According to the question

We are asked to find acceleration

Therefore

We must find "a"

Given that

A vehicle starts from rest and attains a uniform velocity of 20 m/s in 5 seconds

Hence

• u = 0 m/s [starts from rest]
• v = 20 m/s
• t = 5 s

Substituting the values

We get

$a = \frac{20 - 0}{5} m | {s}^{2} \\ a = 4 \: m | {s}^{2}$

Answer 2

Answer:

A vehicle starts from rest and attains a uniform velocity of 20 m/s in 5 seconds

To Find

Acceleration

Solution

We know that

Here

a = Acceleration

u = Initial velocity

v = Final velocity

t = Time

According to the question

We are asked to find acceleration

Therefore

We must find "a"

Given that

A vehicle starts from rest and attains a uniform velocity of 20 m/s in 5 seconds

Hence

u = 0 m/s [starts from rest]

v = 20 m/s

t = 5 s

Substituting the values
