First, we have to do some mental gymnastics and decide what the question means by "different but identical".
Let's assume it's talking about two copies of the same item, like two separate identical twins.
What the question seems to be describing is the situation where both balls are rolling horizontally
across the table toward the edge. One is rolling much faster than the other, but they both reach the
edge and fall off at the same instant.
They will hit the floor at the same instant. The one that was rolling faster before the fall will hit the
floor farther from the foot of the table, but the two "clunks" as they hit will come at the same instant.
Depth. To ascend is to go up, and to descend is go down. We measure the height of things above the ground and the depth of things below the ground.
a bearing is the angle from north moving clockwise 360 degrees a negative bearing is moving counterclockwise from north
There's no proper reason. It was defined as such. Taking 1 as the denominator we can compare between two things easily like:Two trains are moving with following parametersFirst moving 500 km in 7 hrSecond moving 450 km in 6 hrWe have to determine who is faster... Now at unit (means one) hourFirst train is moving (500/7)=71.42 km per hourSecond train is moving (450/6)=75 km per hourSo clearly we can say that the 2nd train is faster.
Let us first analyse the question. The car is travelling at some speed. And it has to stop. What distance will it cover before it stops?Firstly, it is travelling at a speed of 100 kilometers per hour. And the deceleration provided is given in meters per second. So, let us convert all the data into same terms.that is, 100 kmph = 100*1000 meters per hourSo, it is travelling 100,000 metres in one hour. And one hour has 3600 secs.Hence the car is travelling 100000/3600 meters in ONE secondthat is 27.77778 or approx = 27.8 meters/second.Or simply, 100 km/hr = (100*5/18) mts/sec = 27.8 mts/secNow, we have a formula to calculate the distance covered, acceleration and deceleration provided and the initial and final speeds.v2-u2 = 2*a*s ,a is acceleration/deceleration, s is distance, v is final speed, u is initial speed.In this case, final speed is zero and deceleration = negative acceleration02-(27.8)2 = 2*(-10)*s-20*s = - (27.8*27.8)s = 38.642 metersHence the car travels a distance of 38.642 metres before it comes to a stop.
Speed X journey time. (Time actually moving).
20 meters per second
92.2m/s
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.
Two observers could measure a different speed for the same moving object if they are moving at different velocities relative to the object. This is because the speed of an object would appear different depending on the speed and direction of the observer. This effect is known as relative motion.
Air moving parallel to the ground is called horizontal wind or surface wind.
Jack is moving at a speed of 7.5 meters per second.
Looking at the ground beside a moving vehicle helps you judge its
show that you are moving, and in what direction
a dildo wave
Moving an airplane on the ground is called 'taxiing'
The velocity of a person relative to the ground depends on their speed and direction of movement. It is typically measured in meters per second (m/s) or kilometers per hour (km/h) and can be positive (moving forward) or negative (moving backward). This velocity is determined by the person's motion relative to the stationary ground.
When looking out the window, if you focus on a distant building outside the train, it may appear that the train is not moving because the building is not changing position relative to the train. However, if you look at a nearby platform or another train beside yours, you may notice the train's movement compared to these closer reference points, making it appear that the train is indeed moving.
