- Distance=s
Apply second equation of kinematics
Answer:
B. The number of wave cycles that pass through a specific point within a given time period.
The sphere will go up until all the initial kinetic energy be transformed into potential energy.
Intital kinetic energy = m*(vi)^2 / 2
Final potential energy = mgh
mgh = m(vi)^2 / 2 => h = (vi)^2 / (2g)
g = 9.81 m/s^2
vi = (1.5m/s)^2
h = (1.5m/s)^2 / (2*9.81m/s)^2 = 0.115 m
The range is the distance run over the ramp
Using trigonometry, sin(20°) = h /run => run = h / sin(20) = 0.115m / sin(20) = 0.336 m
Answer: 0.336 m
Answer:
0.5 m/s
Explanation:
In solving this, we would be applying the principle of conservation of momentum. This states that momentum is conserved, and thus, Initial momentum has to be equal to the final momentum. This also means that it can be related by the formula
M * u = m * v, where
M = mass of the astronaut
m = mass of the wrench
u = speed of the astronaut
v = final speed of the wrench
70 * u m/s = 1.6 * 22 m/s
70u = 35.2 m/s
u = 35.2/70
u = 0.5 m/s
According to the particle theory, the third theory is that if heated,the particles move faster and then the kinetic energy increases.I think your question relates to fluid friction and it will only increase when an object increases in which will cause it to come intact with more particles.The faster the object moves- The more particles.The greater the attraction between particles or molecules, then the greater the resistance of the molecules to flow past one another.Hope that helped !
