Answer:
Below
Explanation:
First, we need to convert the dimension from cm to m before plugging it into the equation:
32 / 100 = 0.32 m
10 / 100 = 0.1 m
You can use this equation to find the pressure exerted on the ground
Pressure = Force / Area
Plugging our values in.....
Pressure = 16 Newtons / (0.1)(0.32)
= 16 Newtons / 0.032
= 500 N/m^2
Hope this helps! Best of luck <3
Answer:
Part a: The force between the tires and the ground is 765 lbf.
Part b: The force between the pallet and the boulder is 1016 lbf.
Explanation:
From the free body diagram on the Truck, boulder and pallet level
- is the acceleration of truck which is 1 ft/s2
- is the mass of the truck which is 5000 lb or 155.28 slugs
- is the mass of the boulder which is 1000 lb or 31.06 slugs
- is the mass of the pallet which is 200 lb or 6.211 slugs
- is the acceleration of the pallet or boulder which is 0.5 ft/s2
Applying Newton's 2nd Law of Motion on pulley in vertical direction
Part a
Applying Newton's 2nd Law of Motion on Truck in horizontal direction
So the force between the tires and the ground is 765 lbf.
Part b
Applying Newton's 2nd Law of Motion on Boulder in vertical direction
So the force between the pallet and the boulder is 1016 lbf.
Answer:
73.152cm
Explanation:
We have been given:
0.8yards of rain
Problem, convert to cm = ?
Solution:
The problem deals with the conversion from one length dimension to another.
So:
1 yard = 91.44 cm
So 0.8 yards = 0.8 x 9.44 = 73.152cm
The solution to this problem is 73.152cm
I think the answer is c.if current decreases and everything else remains constant,then power will increase
Answer:
Explanation:
Given:
- mass of rocket,
- time of observation,
- mass lost by the rocket by expulsion of air,
- velocity of air,
<u>Now the momentum of air will be equal to the momentum of rocket in the opposite direction: </u>(Using the theory of elastic collision)
