Find the velocity v if a car start from rest and travels 50 m with 2 m/s² acceleration.

Answer 1

$\huge\red{\rm{Answer}}$

Initial velocity of the car (u) = 0 [since, the car starts from rest]

Distance travelled by the car (s) = 50m

Acceleration of the car (a) = 2m/s²

Let final velocity of the car be v m/s.

$\therefore$ v² = u² + 2as

⇒v² = (0)² + 2×2×50

⇒v² = 200

⇒v = √200

⇒v = 14.14 m/s (approximately)

Answer 2

Initial velocity of the car (u) = 0 [since, the car starts from rest]

Distance travelled by the car (s) = 50m

Acceleration of the car (a) = 2m/s²

Let final velocity of the car be v m/s.

\therefore∴ v² = u² + 2as

⇒v² = (0)² + 2×2×50

⇒v² = 200

⇒v = √200

⇒v = 14.14 m/s (approximately).
