Question

a car starts from a stoplight and is travelling with a velocity of 10m/sec east in 20 seconds. what is the acceleration of the car ?​

Answer 1

GiveN :

• Initial velocity (u) = 0 m/s
• Final velocity (v) = 10 m/s
• Time (t) = 20 s

To FinD :

• Acceleration of car

SolutioN :

Use 1st equation of Kinematics

⇒v = u + at

⇒10 = 0 + 20 * a

⇒20a = 10

⇒20a = 10

⇒a = 10/20

⇒a = 1/2

⇒a = 0.5

$\therefore$ Acceleration car is 0.5 m/s²
