Question

a car is moving from rest acquires a velocity of 30 m/s in 10 second what it is acceleration​

Answer 1

➤ Answer

• Acceleration of the car = 3m/s².

➤ Given

• A car is moving from rest acquires a velocity of 30 m/s in 10 second.

➤ To Find

• Acceleration of the car.

➤ Step By Step Explanation

Given that ⤵

• Initial velocity of car = 0 m/s
• Final velocity of car = 30 m/s
• Time = 10 seconds.

We need to find the acceleration of the car.

So let's do it !!

➠ By using first equation of motion

• v = u + at

➠ By substituting the values

$\longmapsto\tt \: v = u + at \\ \\\longmapsto\tt 30 = 0 + a \times 10 \\ \\\longmapsto\tt 30=10a\\\\\longmapsto\tt\cancel\cfrac{30}{10} = a \\ \\\longmapsto\bf{\green{3m/{s}^{2} = a}}$

Therefore, acceleration of the car = 3 m/s²

➤ Equations of motion

There are mainly three equations of motion. They are as follows -

• v = u + at

• s = ut + ½at²

• v² - u² = 2as

Where, u = initial velocity , v = final velocity, t = time, a = acceleration, and s = distance travelled.
