The acceleration of the fire truck is 1.666 m/s².
<u>Step-by-step explanation:</u>
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.
Answer:
The slope of the line is ⇒ B
Step-by-step explanation:
Let us revise the rule of the slope
The rule of the slope of the line is m = , where
- (x1, y1) and (x2, y2) are two points lie on the line
∵ The line passes through the point (-3, 1) and point (4, -2)
→ That means one of them is (x1, y1) and the other is (x2, y2)
∴ x1 = -3 and y1 = 1
∴ x2 = 4 and y2 = -2
→ Substitute them in the rule of the slope above to find it
∵ m = =
∴ m =
∴ The slope of the line is
