The correct answer to go in the blank would be A) The particles are moving faster.
Answer:
Explanation:
The formula that you are working with is F = m*a
Since mass is one part of the formula if you increase the mass, you are going to increase the force.
The second one is much more difficult to answer because it is basically incomplete. This is one way to interpret it. If you start at a certain speed and increase during a known time period then effectively you are defining acceleration which is "a" in the formula.
Without those modifications, there is no answer.
Answer:
The velocity with which the jumper strike the mat in the landing area is 6.26 m/s.
Explanation:
It is given that,
A high jumper jumps over a bar that is 2 m above the mat, h = 2 m
We need to find the velocity with which the jumper strike the mat in the landing area. It is a case of conservation of energy. let v is the velocity. it is given by :
![v=\sqrt{2gh}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B2gh%7D)
g is acceleration due to gravity
![v=\sqrt{2\times 9.81\ m/s^2\times 2\ m}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B2%5Ctimes%209.81%5C%20m%2Fs%5E2%5Ctimes%202%5C%20m%7D)
v = 6.26 m/s
So, the velocity with which the jumper strike the mat in the landing area is 6.26 m/s. Hence, this is the required solution.
Sports like swimming and track are individual races but in the end everyone on the team races come together to make a team placement.
Answer:
A) being influenced by equal amounts of gravity and air resistance.
Explanation:
B) slowing down because of an unbalanced force of air resistance.
False - if it was slowing down, then the velocity would go down.
D) on the ground and is not falling anymore.
False - This would be mistaken as the answer but it is not because if the person is not falling anymore the horizontal line should be at the x-axis, meaning that there is no more velocity.
C) accelerating because of an unbalanced force of gravity.
False - The line would otherwise be going up or down.
