The angle of the projection of the object is 40 degrees The velocity of an object in ‘y’ direction as 40m/s Calculate the range that is covered by the object? Take the time of flight as 6.25 sec to make the calculations easier. Question 1: An object in the influence of an external force is launched at a velocity of 40 m/s in a direction making an angle of 40° upward with the horizontal. The range of the projectile also depends on the angle at which the object is thrown.įor more concepts check out to get quick answers by using this free tool. Like the time of flight and maximum height, the range of the projectile is a function and is linearly dependent on the initial speed of the object under the influence of the external force. This line is represented as a straight horizontal line in the diagrams. There is no acceleration in this direction of the motion since gravity only acts vertically on the object. The range of the projectile is defined as the displacement in the horizontal direction of the motion of the object. So 45 degrees is the only or the best angle at which the maximum height of the projectile can be achieved for any object or projectile following a trajectory under projectile motion. We can solve this quite easily by differentiating the formula and equating it with zero hence getting the answer as 45 degrees. ![]() With the help of formulas, one can calculate at which angle an object or projectile be thrown so that it gains maximum height. The net of both cos and sin is taken as the final angle in the calculations. And cos(α)stands for the horizontal component of the angle.sin(α): stands for the vertical component of the angle.h is the net height from which the object or the projectile has been thrown.V₀ is the vertical velocity of the object under influence of external force.The formula for the projectile range hence may be written as d = V₀ * cos(α) * / g In this particular case, the time spent flying upwards is much shorter than the time when the object is falling down in the same trajectory (time from reaching the maximum height to striking the ground in the same projectile or trajectory). Launch from an elevation (in this case the initial height > 0) And hence this formula can be used as the standard formula for determining the range of the object under the influence of external force from a net height of zero.Ĭase 2. Knowing the trigonometric identity of sin(2 * x) = 2 * sin(x) * cos(x), we can rewrite the final formula as d = V₀² * sin(2 * α) / g. Velocity in our case is the horizontal velocity Vx = V0 * cos(α), and time to reach the ground is a value we've already calculated is as followĭ = V * t = V₀ * cos(α) * 2 * V₀ * sin(α) / g g is the gravity of the place in which the experiment is being done(for most of them it would be earth, hence the value of ‘g’ can be taken as 9.8 m/s/s)įrom this equation, we will find t, which is the time of flight to reach the ground t = 2 * V₀ * sin(α) / gĪlso, we know that the maximum distance of the projectile can be found from the simple relation of the motion in a straight path defined by d = V * t.Alpha (α) is the angle at which the object or the projectile is thrown in the air.T is the time taken for the projectile motion to complete its trajectory.Here V₀ is the vertical velocity of the object under influence of external force. ![]() The projectile range is the distance traveled by the object when it returns to the ground (so y, the horizontal component=0) 0 = V₀ * t * sin(α) - g * t² / 2 To find the formula for the range of such a projectile or the object, let us start from the basic equation of motion. Air resistance of all directions is neglected in all calculations because as the matter of fact the air resistance is generally negligible for any object on the earth.ĬASE 1: Launch of the object under the influence of external force from the ground (here, the initial height is taken as 0) table, building, bridge, inclined place, etc.). Let us split the equations into two cases for easy and better understanding: when we launch the projectile from the ground, that is the net height is taken to be zero, and when the object is thrown from some initial height (for example. ![]()
