If two cars drive off a cliff road in a completely horizontal direction Car A driving 80 meters per second and Car B at 20 meters per second which hits the ground first?

They hit the ground at the same time. Both are accelerated downward by gravity at the same rate (9.8m/sec2), so given a level ground surface below, they will complete the vertical fall in virtually the same amount of time. There are slight variables such as air resistance, because the faster car will travel farther out horizontally from the cliff edge and be moving faster at impact.

What is the definition of inclined plane?
It is simply a plane surface making an angle with the horizontal (ground).
Which plane is the only horizontal plane?
it is the Transverse plane. the transverse, or horizontal plane is a crosswise plane that runs parallel to the ground. this imaginary cut would divide the body or its parts into upper and lower portions.
A plane headed due E is traveling at airspeed of 190 mph The winds are moving with constant speed in the direction 240 degrees If the ground speed of the plane is 95mph what is the speed of the winds?
To find the speed of the winds, we can use the concept of vector components. The ground speed of the plane (95 mph) is the result of the vector sum of the airspeed of the plane (190 mph) and the speed of the winds (w mph). We can find the horizontal component of the airspeed by multiplying 190 mph by the cosine of the angle between the airspeed and the ground direction (240 - 90 = 150 degrees). Thus, the speed of the winds is 70 mph.
A rock is dropped from a height of 60 m and is in a free fall what is the velocity of the rock as it reaches the ground 3.5 seconds later?
After 3.5 seconds of free-fall on or near the surface of the Earth, (ignoring effectsof air resistance), the vertical speed of an object starting from rest isg T = 3.5 g = 3.5 x 9.8 = 34.3 meters per second.With no initial horizontal component, the direction of such an object's velocitywhen it hits the ground is straight down.
The staircase rises 52° from the ground and a vertical distance of 12 yards. How much horizontal distance does the staircase cover Round to the nearest tenth?
9.4 yards i think
What direction of ground motion is usually recorded in a land survey?
horizontal
Which projectile would hit the ground faster one projected at 20 meters per second horizontally or one projected at 20 meters per second in a direction other than horizontal no air?
If the non-horizontal projectile is launched abovehorizontal, thenit's the second one to hit the ground, after the horizontal one.If the non-horizontal one is launched below horizontal, then it'sthe first to hit the ground, before the horizontal one.
When during a jump is your speed zero?
Your vertical speed is zero when you're at the highest point of your jump. After that, itbegins to grow again, but in the downward direction. Your vertical speed is the samewhen you hit the ground as it was when you left the ground, but in the opposite direction.Your horizontal speed doesn't change. It's the same when you hit the ground as it waswhen you left the ground, and in the same direction.
What is horizontal markings?
Horizontal markings are markings (such as painted or etched lines) that are horizontal (or parallel to the ground).
A 5 kg object is thrown from the top of a building 275m aboce some level ground It is released at a speed of 45 m per s initially along the horizontal direction?
THE QUESTION: 2) A 5 kg object is thrown from the top of a building, 275m aboce some level ground. It is released at a speed of 45 m/s, initially along the horizontal direction. (A) What are the magnitude and direction of its velocity at impact on the ground below (B) what momentum does it have at impact (C) What KE does it have just before impact (D) What is the average force during the impact?
Give the 4 difference between horizontal and vertical centering?
Horizontal Alignment includes a straight path, curves, or deviation in a horizontal direction. Vertical Alignment includes vertical curves and gradients on the ground. But it is difficult to change the alignment once the road is constructed, so care has to be taken in finalizing the alignment.
What is marks?
Horizontal markings are markings (such as painted or etched lines) that are horizontal (or parallel to the ground).
How would you use the word horizontal in a sentence?
the word horizontal means: flat or level: a horizontal position. "The line is horizontal to the ground" would work.....
What is the motion parallel to the ground?
horizontal motion
A shell is fired from the ground with an initial velocity of 1600m s at an angle of 64 to the horizontal What is the shells horizontal range?
If a shell is fired from the ground with velocity of 1600 m and an angle of 64 to the horizontal then it would have a horizontal rang of 55.0. This is considered math.
What is air moving parallel to the ground called?
Horizontal force is motion parallel to the ground.
What shape is the sheep's pupil?
Sheep and goats have horizontal, oval pupils.
