Answer:the car was traveling at a speed of 80 ft/s when the brakes were first applied.
Step-by-step explanation:
The car braked with a constant deceleration of 16ft/s^2. This is a negative acceleration. Therefore,
a = - 16ft/s^2
While decelerating, the car produced skid marks measuring 200 feet before coming to a stop.
This means that it travelled a distance,
s = 200 feet
We want to determine how fast the car was traveling (in ft/s) when the brakes were first applied. This is the car's initial velocity, u.
Since the car came to a stop, its final velocity, v = 0
Applying Newton's equation of motion,
v^2 = u^2 + 2as
0 = u^2 - 2 × 16 × 200
u^2 = 6400
u = √6400
u = 80 ft/s
Answer: There are 418 sheets needed to cut all the required apples and leaves.
Explanation:
Since we have given that
Number of apples = 1045
Number of leaves = 1463
From a sheet of paper,
Number of apples can be cut = 5
Number of leaves can be cut = 7
Let the number of sheets of paper be x
So,
Number of sheets of paper required to cut 1045 apples is given by
Similarly,
Number of sheets of paper required to cut 1463 leaves is given by
So, total number of sheets is required to cut 1045 apples and 1463 leaves is given by
Hence, there are 418 sheets needed to cut all the required apples and leaves.
Answer:
The probability is most likely to occur
Step-by-step explanation:
The correct answer would be that Carl is 4 years old. If John is 20 years older than Carl, that would make him 24. 24 + 4 = 28 years. Therefore, Carl must be 4 years old.
