Answer:
1) The girl's acceleration at time 't' is,
m/s²
2) The girl's acceleration at time 't₁' is,
m/s²
3) The girl's acceleration at time 't₂' is,
m/s²
Explanation:
Given data,
The initial walking speed of the girl, u = 0
The speed of the girl at the time 't' 3 s is, v₁ = 1.4 m/s
The time period the girl walked at the speed 1.4 m/s is, t₁ = 6 s
The girl slows down and comes to a stop during a period, t₂ = 10 s
1) The girl's acceleration at time 't'


m/s²
2) The girl's acceleration at time 't₁'


m/s²
3) The girl's acceleration at time 't₂'


m/s²
When the student uses a straw to blow a stream of air between the papers, the <span>two pieces of paper come together because the pressure between the two was lowered. This follows the Bernoulli’s Principle. Hope this answers the question. Have a nice day.</span>
Answer: The right answer is b)
Explanation:
By definition, acceleration is the change in velocity (in module or direction) over a given time interval, as follows:
a = (v-v₀) / (t-t₀)
If we take t₀ = 0 (this is completely arbitrary), we can rewrite the equation above, as follows:
v = v₀ + at
We can recognize this function as a linear one, where a represents the slope of the line.
If a is constant, this means that the relationship between the change in velocity and the change in time remains constant, in other words, in equal times, its velocity changes in an equal amount.
Let's suppose that a = 10 m/s/s. (Usually written as 10 m/s²).
This is telling us that each second, the velocity increases 10 m/s.
