Answer:
10.6 s
Explanation:
First of all, let's convert both speeds into m/s:
- Cheetah:
- Gazelle:
Taking as reference the position x = 0, the position of the cheetah at time t is
while the position of the gazelle, which starts 68.8 m ahead, is
The cheetah catches the gazelle when the two positions are equal:
and substituting the speeds and solving for t, we find the time at which the cheetah reaches the gazelle:
Without magnetic domains a magnet would have its magnetism. Magnetic domains are clusters of iron atoms that line up in the same direction when magnetized. When not magnetized the iron atoms scatter.
To calculate the horizontal distance traveled by the shot if it leaves the athlete's hand at a height of 2.20 above the ground we can get the root of the quad equation for time are t=-0.24 or t =1.84 taking the t = 1.84, so the equation will be:
x = 15.6cos(30) * 1.86, x = 24.79m
Answer:
The answer to your question is: D.
Explanation:
Distance refers to the amount of space between two points, it is a scalar quantity.
Displacement refers to the space between two points, measure from the minimum path linking them, it is a vector quantity.
I'm not agree with these answers, because the total distance is approximately 500km.
A) The distance traveled is 300 km. This answer is not correct.
B) Distance is 300 km and displacement is 0 km. This answer is not correct because the displacement is also 500 km.
C) Distance is 300 km/hour and displacement is 300 km.
300 km/h is a measure of speed not of distance, this option is wrong.
D) Both distance traveled and displacement are 300 km. I think this is the correct answer because distance and displacement measure the same. but I think both measure 500 km.
