Answer:
B. 0.50 meters/second^2
Explanation:
Given:
- mass of table (m) = 10.0 kg
- Eli's force (F1) = 120 N
- Andy's force (F2) = -125 N
Arranging Formulas and Substituting Values, Part 1:
- F = F1 + F2
- F = 120 + (-125)
- F = -5 N
- The -5 means that the table will move along the direction of the force applied by Andy.
Arranging Formulas and Substituting Values, Part 2:
- m * a = F
- a = F / M
- a = -5 / 10.0 kg
- a = -0.5 m/s^2
Confused about how much fun you have done to the other day and then I will be sure you guys are gonna right I know you have your own words but you know that I don’t think you know what I mean but you don’t
Gravitational force decreases with increasing distance. So it decreases!
Explanation:
Given that,
Initial speed of a ranger, u = 36.2 mi/h
Distance dove by the ranger, d = 205 ft
Due to the application of brakes, the acceleration reached is 8.83 ft/s².
We need to find the maximum reaction time allowed if she is to avoid hitting the deer.
We know that,
1 mph = 1.46667 ft/s
36.2 mi/h = 53.09 ft/s
Let t is time.
Using second equation of kinematics to find it as follows :
The above is a quadratic equation. We need to solve it for t as follows :
Hence, 416.01 seconds is the maximum reaction time allowed if she is to avoid hitting the deer.
Answer:
V= 4999.5 m/s
Explanation:
Given that
mass ,m= 605 gm
Length ,L= 0.75 m
width ,b= 0.01 m
height ,h= 0.03 m
frequency ,f= 3333 Hz
We know that
2 Length = Wavelength
λ= 2 x L
λ = 2 x 0.75 m
λ= 1.5 m
The speed V
V= f x λ
Now by putting the values
V= f x λ
V= 3333 x 1.5 m/s
V= 4999.5 m/s
