Question

A car accelerates from zero to a speed of 110

km/hr in 15 seconds. What is the car's rate of
acceleration?

Answer 1

The car's rate of acceleration : a = 2.04 m/s²

Further explanation

Given

speed = 110 km/hr

time = 15 s

Required

The acceleration

Solution

110 km/hr⇒30.56 m/s

Acceleration is the change in velocity over time

a = Δv : Δt

Input the value :

a = 30.56 m/s : 15 s

a = 2.04 m/s²
