Question

A scooter acquires a velocity of 36 km per hour in 10 second just after the start.calculate the acceleration if the scooter​

Answer 1

We have been given that a scooter acquires a velocity of 36 km/h in 10 seconds just after start from rest.

We have to find acceleration of scooter.

Solution

As the scooter acquires velocity of 36 km/h just after start, so it starts from rest.

So, initial velocity of scooter = 0 m/s

Again, final velocity = 36 km/h

➝ Final velocity = 36 × (5/18)

➝ Final velocity (v) = 10 m/s

Using first equation of motion :

➝ v = u + at

Putting all values :

➝ 10 = 0 + a × 10

➝ 10 = 10a

➝ a = 10/10

➝ a = 1 m/s²

Therefore,

Acceleration of scooter = 1 m/s²

Answer 2

Answer:

Explanation:

Correct Question :-

A scooter acquires a velocity of 36 km/h in 10 seconds just after the start. Calculate the acceleration of the scooter.

Answer :-

Given :-

Initial velocity, u = 0 (As scooter starts from rest)

Final velocity, v = 36 km/h = 36 × 5/18 = 10 m/s

Time, t = 10 seconds

To Find :-

Acceleration, a = ??

Formula to be used :-

1st equation of motion i.e v = u + at

Solution :-

Putting all the values, we get

v = u + at

⇒ 10 = 0 + a × 10

⇒ 10 = 10a

⇒ a = 10/10

⇒ a = 1 m/s²

Hence, the acceleration of the scooter​ is 1 m/s²
