Question

A car starts moving from rest; If it gains avelocity of 72km/ht after to seconds what is the acceleration of the car.​

Answer 1

The correct answer is 10 m/s² .

Answer 2

10 m/s²

Step-by-step explanation:

Given

• u = 0 (initial velocity as it is at rest)
• v = 72 km/h x 5/18 = 20 m/s
• t = 2s

Solving

• v = u + at
• 20 = 0 + 2a
• 2a = 20
• a = 10 m/s²
