Question

If the initial velocity of a car is 5m/s and the final velocity is 10m/s in 5s then the acceleration is

Answer 1

the acceleration is 15m/s

Answer 2

Acceleration of car is 1 m/s²

Solution

Given that the initial velocity of a car is 5m/s and the final velocity is 10m/s in 5s .

We have to find acceleration of car.

Explanation

From the given data we have ;

• Initial velocity (u) = 5 m/s
• Final velocity (v) = 10 m/s
• Time (t) = 5 s

Now using first equation of motion :

→ v = u + at

Substituting values,

→ 10 = 5 + a * 5

→ 10 = 5 + 5a

→ 10 - 5 = 5a

→ 5 = 5a

→ a = 5/5

→ a = 1 m/s²

Hence,

Acceleration of car = 1 m/s²
