Question

a car started from the rest and travelling with a velocity of 20 metre per second in 10 second what it is acceleration​

Answer 1

Answer:

Explanation:

Given :-

Initial Velocity of the car, u = 0 m/s

Final Velocity of the car, v = 20 m/s

Time Taken by the car, t = 10 seconds

To Find :-

Acceleration

Formula to be used :-

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

Solution :-

Putting all the values, we get

⇒ v = u +at

⇒  20 m/s = 0 + a × 10s

⇒  a = 20m/10s

⇒  a = 2 m/s²

Hence, the acceleration​ of car is 2 m/s².

Answer 2

» A car started from the rest and travelling with a velocity of 20 m/s in 10 s.

Here..

• Initial velocity (u) = 0 m/s

(because it is given in question that car start from rest)

• Final velocity (v) = 20 m/s

• Time (t) = 10 s

___________ [ GIVEN ]

• We have to find the acceleration (a) of the car.

_____________________________

We know that..

=> v = u + at

(First Equation Of Motion)

Put the known values in above formula

→ 20 = 0 + a(10)

→ 20 = 10a

→ 2 = a

→ a = 2 m/s²

____________________________

Acceleration of the car is 2 m/s².
