Calculating the average speed is simple using the formula <span>speed = distance/time</span>
Answer:
25 m/s
Explanation:
1 km/h = .277778 m/s, so 90 x .277778 = 25
The average kinetic energy of the gas would also be constant since the temperature of the gas is not changing.
<h3>What happens to the average kinetic energy?</h3>
The kinetic energy is the energy of the particle that is motion. We know that the kinetic energy of the gas is proportional to the temperature of the gas. As the temperature increases, the kinetic energy of the particles of the gas increases.
Now we can see that the gas has been maintained at a constant temperature and a constant volume and that the particles of the gas collide with each other. This implies that the average kinetic energy of the gas would also be constant since the temperature of the gas is not changing.

Answer:
velocity = 8.84 m/s
Explanation:
given data
radius r = 11.9 m
acceleration of gravity g = 9.81 m/s²
static friction μ = 0.67
to find out
how fast can the car go without skidding
solution
we get here velocity that is car go without skidding is express as
force = 
force = μ × mg
μ × mg = 
v² = μ × r × g
v =
..................1
v = 
v = 8.84 m/s
velocity = 8.84 m/s
Answer:
The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.
