I = mΔv
I = 2.5 x (7.5 - 0) = 18.75 kg.m/s
Now, considering that the ball´s initial velocity was zero, we have:
1.45 x 0 + 2.5 x 7.5 = 1.45 x V
1.45V = 18.75
V = 12.93 m/s
These are all the characteristics of what is called the adiabatic process. This process occurs when there is no transfer of heat between the surroundings and the thermodynamic system. This is a key process for thermodynamics and it is of great importance for the first law of thermodynamics.
Answer:
After several thousand more years, mesotrophic lakes gain nutrients from the fallen, decayed leaves from deciduous trees, decayed shoreline plants, decaying aquatic plants, and the remains of fish and other water creatures.
Explanation:
plz give me brainliest
Answer:
Though no question is specified here but let analyzed experiences of each
Explanation:
1. Required a force to stop it (Law of inertial). Constant acceleration
2. will have reduced acceleration (deceleration)
3. Uniform acceleration may set in. it accelerate
4. maximized it speed since no friction affect it motion
5. accelerating. Vo=0 and V gradually increased
6. less or no friction opposes the motion
7. It experience reduce motion based on air friction
8. constant acceleration due to gravity
9. g can be a bit affected but still about equal
Answer:
24 m
Explanation:
The motion of the car is a uniformly accelerated motion (=at constant acceleration), therefore we can find the distance covered by using the following suvat equation:
where
s is the distance covered
u is the initial velocity
t is the time elapsed
a is the acceleration
For the car in this problem:
u = 0, since the car starts from rest
is the acceleration
t = 4 s is the time elapsed
Therefore, the distance covered is:
