Question

A car starts from rest and accelerates and accuires velocity of 15m/s in 2 minutes

Answer 1

Answer:

Acceleration = 0.125 m/s²

Explanation:

Initial velocity = u = 0m/s (Body starts from rest)

Final velocity = v = 15m/s

Time taken = t = 2min = 2*60 = 120s

We know that

Acceleration = Change in velocity/Time

a = (v - u)/t

a = (15 - 0)/120

a = 15/120

a = 1/8 m/s²

a = 0.125 m/s²
