Question

a car start from rest and acquire a velocity of 20m/s in 2sec . the acceleration is​

Answer 1

GIVEN:

Initial velocity = 0

Final velocity = 20m/s

Time taken = 2 second

TO FIND :

the acceleration of car.

FORMULA USED:

V = U + at

where :-

• V = Final velocity
• U = Initial velocity
• a = acceleration
• t = time taken

SOLUTION :

To find acceleration use the given Formula :-

V = U + at

put :-

Initial velocity ( U) = 0

Final velocity (V) = 20m/s

Time taken (t) = 2 second

⟹20 = 0 + 2a

⟹20/2 = a

⟹10 m/s² = a

ANSWER:

Acceleration = 10 m/s²

More Formulae :-

1. v = u+at

2. v²-u²= 2as

3. s = ut+1/2 at²
