<span>While you're going to the store, your acceleration changes. Some times it increases your overall speed sometimes it reduces it. Constant acceleration does not occur because it would mean that you would constantly accelerate and eventually go past the store. Even reduction of speed is a type of acceleration in physics. When you reach it, we can then calculate how much your velocity was on average and analyze how changing acceleration would've affected it.</span>
Answer:
v = 108 m/s.
Explanation:
Given that,
The position of a particle moving on a straight line is given by :
We need to find the instantaneous velocity at t=5s.
Velocity,
So,
Instantaneous velocity at t = 5 s will be :
v = 18+18t
v = 18+18(5)
= 18 + 90
= 108 m/s
So, the instantaneous veloctiy at t=5s is 108 m/s.

Answer:
P=160000Pa
Explanation:
You haven't specified what to calculate
But looking at the parameters I think the question is asking to calculate the pressure exerted.
Pressure=Force/Area
P=40000/0.25m²
P=160000Pa
