For these calculations, air resistance is neglected and acceleration due to
gravity is assumed to be -9.8 m/s2. It is assumed the the rock was thrown horizontally.
Velocity is a vector, with an x component and a y component. The x component will not change, so the x component at the point of impact will be 8 m/s. The y component of the velocity is initially zero, and the acceleration is -9.8 m/s2. The final y component of the velocity can be found using the formula
vy2 = v0y2 + 2(a)(h)
so vy2 = 2(-9.8)(-100), so vy is 44.3. The x and y components of the velocity vectors now need to be put to together using the Pythagorean theorem. So
v2 = 44.32 + 82 so the final velocity is 45.02 m/s. The angle relative to the ground can be found using the tangent. tan-1(44.3/8), which is 79.8 degrees.

How many mph is13.00 in 100m dash?
I was thinking the same thing but I found a solution:Basically 1 second= 0.00027778 hours.13mph- 0.06214(calculation of length of 100m)÷(0.00027778X13(your speed))This equals=17.21 seconds as your 100m dash time.It might look complicated but I simplified it.
How many meter in 3 hectors?
If you mean HECTARE- that is a unit of land measurement of 10,000 sq. meters (100m by 100m). So 3 hectares would be 30,000 square meters.
A sprinter runs 200m west and 100m east her displacement is?
displacement is the measure of the distance from the starting and ending points, AND the direction. it doesnt matter that she ran 300m total. heres the math for displacement: point b (the direction with the larger number) - point a(direction with the smaller number the direction will be point b's direction. so, plug it in. 200m west - 100m east =100m west ^^ if u wer to draw displacement, you would not need 2 draw the 200m west or the 100m east; you would imply draw the starting point and then 100m west, and draw a straight line connecting them. ^^ hope this helps!

What is the fastest 100m dash by a freshman?
The fastest 100m dash by a freshman is 10.05 seconds, achieved by Anthony Schwartz at the 2018 Florida High School Athletic Association (FHSAA) Outdoor State Championships.
What is the velocity if the distance is 100m and the speed is 150 seconds?
Velocity is a vector quantity that includes both speed and direction. If the distance is 100m and speed is 150 seconds, a velocity cannot be calculated without a direction component. Velocity is typically expressed as distance traveled per unit time in a specific direction.

When an object moves with inconstant velocity does its average velocity differ from its instantaneous velocity?
Generally it is a Yes. Instantaneous velocity is the exact velocity at a particular time in the course of the movement. However, average velocity is the average of all the instantaneous velocity over a period of time. It is also known as speed in everyday life. As a result, the movement of an object over a time period under varying velocity denotes a varying instantaneous velocity which could be different from the average velocity. It is however, possible that the instantaneous velocity equates to the average velocity at a certain point over the duration of movement. For example, a ball is traveling at instantaneous velocity of 99m/s at t=1s , 100m/s at t=2s and 101m/s at t=3s. the average velocity over the 3s period is hence 100m/s which coincides with the instantaneous speed at t=2s.
Calculate average velocity and average speed?
sharon sprinter changes her speed from 4.5m/s to 7.5m/s in the middle 1.5 seconds of a 100m race. what is her average velocity for this time period?
How can average velocity be zero if traveled 100m?
This question revolves around the idea of vector quantities. Vector quantities involve two factors: magnitude and direction. Velocity (as well as average velocity) is a vector quantity. The given value of 100m is a magnitude of a distance which is a scalar quantity. Average velocity can be represented as below (all V's represent velocity, not speed). Vavg = ½ (Vi + Vf ). Let us say that an object was traveling at an initial velocity of 15m/s [East] for a certain amount of time. Afterward, the object suddenly travels at a final velocity of 15m/s [West] for a certain amount of time. In total, the object may have traveled 100m. Because the direction of the two velocities are opposite, the magnitude of the two values are opposite of one another. In other words, Vavg = ½ (0m/s) = 0. Therefore, it is important to always think about the direction an object is travellng when a vector quantity is involved.
7 A 900N mountain climber scales a 100m cliff. How much work is done by the mountain climber?
The work done by the mountain climber can be calculated using the formula: work = force × distance × cos(θ), where θ is the angle between the force and the displacement. In this case, the force is 900N, the distance is 100m, and assuming the angle is 0 degrees (straight up), the work done would be 900N × 100m × cos(0°) = 900N × 100m × 1 = 90,000 Joules.

How long would it take to fall 100 meters?
It all depends on the initial velocity at which you fell, and whether air resistence is present, etc. If you are simply in a state of free fall, your time to reach the ground would be d=100m v1=0 a=9.8 <- acceleration of gravity on earth t=unknown d = Vi*t + 1/2 a t^2 100m=0*t+1/2(9.8) *t^2 100m=4.9*t^2 sqrt:(100m/4.9)=t
