题目 求解英语数学the height of a projectile at t seconds is given by the formula: h=2100t-490t^2. How long can it stay up in the air. 相关知识点: 试题来源: 解析能呆在空中,则h>0即2100t-490t^2>07t^2-30t<00<t<30/7即呆在空中最长时间为 30/7 秒 ...
The projectile formula is an equation that is used to calculated the height of a projectile at any given time. The formula has four variables: final height (H_f), initial height (H_0), initial velocity (v_0), and time (t). If three of the four variables are known, then the fourth...
Ok so this is what i need to do, to find the maximum height of the projectile in it's flight path; 1) Work out the angle from the base of the trebuchet, to the point where the ball is released, by doing tan-1(y/x). y is the height from the base of the trebuchet, to the...
Vertical Velocity of Projectile Motion Lesson Summary FAQs Activities How to find vertical and horizontal components of a velocity? A simple way to find the vertical and horizontal components of velocity is by forming a right triangle. Make sure that the velocity vector is the hypotenuse of the...
For example, the free-fall motion of any object in a horizontal path with constant velocity is a type of Projectile Motion. This motion has many terms for computations such as horizontal velocity, vertical velocity, Maximum height, time of flight, etc. In this article, we will discuss the ...

Therandom variablesfollowing the normal distribution are those whose values can find any unknown value in a given range. For example, finding the height of the students in the school. Here, the distribution can consider any value, but it will be bounded in the range say, 0 to 6ft. This ...
Projectile motion involves the motion of an object in (usually) two dimensions under the force of gravity. The behavior of the object in the x-direction and in the y-direction can be described separately in assembling the greater picture of the particle's motion. This means that "g" appears...
