Er uvay, vvildt is your average velocity!
A fire truck is responding to an emergency. It accelerates from 0 to 66
km/hr in 11 seconds. What is its rate of acceleration?
13

The acceleration of the fire truck is 1.666 m/s².

Step-by-step explanation:

Acceleration is the measure of change in velocity with respect to time. So as the initial velocity of the fire truck is given as 0 km/hr and the final velocity is given as 66 km/hr. So at first the truck is at rest and on switching on the engine, the truck gets to the velocity of 66 km/hr in 11 seconds.

But first the units of velocity should be changed from km/hr to m/s

1 hour = 3600 seconds

1 km = 1000 m

So,

Converted Velocity = 18.33 m/s

Then, the acceleration will be

Acceleration = 1.666 m/s²

So, the acceleration of the fire truck is 1.666 m/s².
