The acceleration of this car is equal to 5 .
<u>Given the following data:</u>
- Initial velocity = 0 m/s (assuming it's starting from rest).
- Final velocity = 10 m/s.
- Time = 2 seconds.
To determine the acceleration of this car:
<h3>How to calculate acceleration.</h3>In Science, the acceleration of an object is calculated by subtracting the initial velocity from its final velocity and dividing by the time.
Mathematically, acceleration is given by this formula:
<u>Where:</u>
- V is the final velocity.
- U is the initial velocity.
- is the time measured in seconds.
Substituting the given parameters into the formula, we have;
Acceleration, a = 5

Answer:
Hence the pressure is
Explanation:
Given data
Q=1500 J system gains heat
ΔV=- 0.010 m^3 there is a decrease in volume
ΔU= 4500 J internal energy decrease
We know work done is
W= Q- ΔU
=1500-4500= -3000 J
The change in the volume at constant pressure is
ΔV= W/P
there fore P = W/ΔV= -3000/-0.01= 3×10^5
Hence the pressure is
