Question

A car is moving with the acceleration 2m/s from rest. find the distance travelled by the car in the 5thsecond ​

Answer 1

AnswEr :

›»› The distance travelled by the car in the 5 second is 25 m.

Given :

• Initial velocity of car = 0 m/s.
• Acceleration produced by car = 2 m/s².
• Time taken by car = 5 second.

To Find :

• Distance travelled by the cat in the 5 second = ?

Solution :

As we are given with the initial velocity of car, acceleration produced by car, and time taken by the car so, we will use the second equation of motion, that is,

→ s = ut + ½ at².

Here,

• s is the Distance travelled in m.
• u is the Initial velocity in m/s.
• t is the Time taken in second.
• a is the Acceleration in m/s².

Substituting the given values in the equation, we get :

→ s = 0 * 5 + ½ * 2 * (5)²

→ s = 0 + ½ * 2 * (5)²

→ s = 0 + ½ * 2 * 25

→ s = 0 + 1 * 25

→ s = 0 + 25

→ s = 25

Hence, the distance travelled by the car in the 5 second is 25 m.

Extra Brainly Knowledge :

★ Three equations of motion :

First equation of motion :

• v = u + at.

Second equation of motion :

• s = ut + ½ at².

Third equation of motion :

• v² = u² + 2as.

Answer 2

Answer:

Given:-

• A car is moving with the acceleration 2 m/s from rest and time taken is 5 secs.

To Find:-

• What is the distance traveled by the car in the 5 second.

Solution:-

Given in the question that is,

☛ u = 0 m/s

☛ a = 2 m/s

☛ t = 5 second

Now, we have to use formula that is,

✪ s = ut + $\dfrac{1}{2}$at² ✪

⇰ s = 0(5) + $\dfrac{1}{2}$ × (2)(5)²

⇰ s = 0 + $\dfrac{1}{2}$ × 2 × 25

⇰ s = 0 + 25

⇰ s = 25 m

Therefore, the distance traveled by the car in the 5 second is 25 m .
