Answer:
The driver can avoid the child because at the time she brake 1.6s the car just move 20.928 meters so is far to the 65 meters where the kind is
Distance= 20.928 m
Explanation:
Distance the kid is 65m so the car have to be less in the time she is braking
So to calculated the distance while she is braking
The distance of the car is less than the distance of the kid in his bike
So she didn't hit him
Answer:
Explanation:
Work is the product of force and distance, so the formula is:
The work is 6.00 Joules, but
- 1 Joule (J) is equal to 1 Newton meter (N*m).
- Therefore, the work of 6.00 J is equal to 6.00 N*m
The force is 2.50 Newtons.
The known values are:
Substitute the values into the formula.
We are solving for distance, so we must isolate the variable, d. It is being multiplied by 2.50 Newtons and the inverse of multiplication is division. Divide both sides by 2.50 N.
The units of Newtons cancel out.
The force was applied to the rock over a distance of <u>2.40 meters</u> and choice <u>C</u> is correct.
<u>Answer</u>:
The value of the temperature 15 degrees Celsius in degrees Kelvin is 288 degrees
<u>
</u><u>Explanation</u><u>:
</u>
Given:
Value of temperature= 15 degrees Celsius
To find:
Temperature in kelvin=?
Solution:
We Know that,
Celsius scale = Kelvin scale – 273
Re-arranging the formula,
Kelvin scale = Celsius scale + 273
Substituting the value we get,
Kelvin scale reading = Celsius scale + 273
Kelvin scale reading = 15 + 273
Kelvin scale reading =288K
Thus the kelvin value of 15 degree Celsius is 288 degrees
Answer:
v = 6.95 m/s
Explanation:
Given that,
A diver is on a board 1.80 m above the water, s = 1.8 m
The initial speed of the diver, u = 3.62 m/s
Let v is the speed with which she hit the water. It will move under the action of gravity. Using the equation of motion as follows :
So, she will hit the water with a speed of 6.95 m/s.
Answer:
For Jin, the speed of the arrow is 13 m/s, and for the archer, the speed of the arrow is 17 m/s.
