Acceleration
- a=v-u/t
- a=20-0)6.6
- a=20/6.6
- a=3.03m/s²
Now
Apply Newtons second law
To find frictional force we need coefficient of friction which is not given .
generally for car case the value of coefficient is 0.6-0.8 .
Putting max 0.8
- f=$\mu$ N
- f=0.8(3030)
- f=2424N
Note:
Last part is assumption not accurate
Answer: a= 37m
Explanation: V= 15 m/s (Velocity) t= 0.41s (time) formula: a= v/t
15 m/s / 0.41 (15 divided by 0.41) = 36.583m
There are 2 significant digits, 36, you look at the third digit, either round up or down in this case up to 36. a= 37m
The x and y-components of the vector R is 44.15i + 23.47j.
The given parameters:
- Magnitude of vector R = 50 m
- Position of vector R = 28 degrees
<h3>What is component vectors?</h3>
- This is the representation of vectors in x and y-coordinates.
The x and y-components of the vector R is calculated as follows;

R is a unit vector.
The plot of vector R is in the image uploaded.

a clock .. and i guess a non functioning clock ?
To develop this problem we will apply the Archimedes model. As well as the definitions of Weight based on mass and acceleration. The first in turn will be considered under the relationship of Density and Volume. From the values given we have to:


Since it is in equilibrium, the weight of the object will have a reaction from the water, which will cause the sum of forces between the two objects to be zero, therefore





The value of gravity is canceled because it is a constant



The portion of the object that is submerged corresponds to 82%, while the portion that is visible, above the water level will be 18%
