The actual mechanical advantage, the velocity ratio, and the length of the slope if the height of the slope is mathematically given as
<h3>What are the actual mechanical advantage, the velocity ratio, and the length of the slope if the height of the slope is 10 m?</h3>
Question Parameters:
A block of weight 5000 N is pushed up a slope by a force of 250 N.
Generally, the equation for the actual mechanical advantage is mathematically given as
A=Fout/Fin
A=5000/250
A=20
b)
the velocity ratio is given by the distance moved by the effort divided by the distance moved by the load
Therefore
VR=250/5000
VR=0.05
c)
the length of the slope if the height of the slope is 10 m
Assume the slope is at an angle of 30
Hence
sin 30=10/x
x=20m

Question: which statement provides a complete scientific discription of an object in motion?
Answer: the marble moved 30 cm north in 6 seconds.
Explanation: motion is a change in position of an object over time an object's motion cannot change unless it is acted upon by a force

Answer:
Part A:
Time taken by the snake to reach its top speed is 1.28571 sec.
Part B:
Snake travels 2.0828 m in that time
Part C:
Mongoose have a chance to catch the black mamba
Explanation:
Part A:
According to first equation of motion:
v_f is top speed
v_i is initial or minimum speed
t is time
a is acceleration
Time taken by the snake to reach its top speed is 1.28571 sec
Part B:
According to Second equation of motion:
v_i=0
Snake travels 2.0828 m in that time
Part C:
Distance covered by black mamba is 2.0828 m which is less than its length 3.12 m
2.0828 m<3.12 m
Mongoose have a chance to catch the black mamba
Answer:
470 N.
Explanation:
Using equations of motion:
S = vi*t + 1/2*(a*(t^2))
Given:
S = 0.65 m
t = 1.5 s
vi = 0 m/s
0.65 = 1/2 * (a * (1.5)^2)
a = 1.3/2.25
= 0.578 m/s^2
Force = mass * acceleration due to gravity
= 92 * 0.578
= 53.16 N
Total force = 420 + 53.16
= 473.16 N
= 470 N.
The tangent of that angle is 17.63/100 = 0.1763 .
My calculator says that the angle with that tangent is 9.9985° .
10° is awfully close, and it's a much easier answer.
(It's less than 0.015% wrong.)
