WebFeb 18, 2024 · The initial velocity for each axis is then v 0, x = v 0 cos α and v 0, y = v 0 sin α where α is the velocity vector angle measured anticlockwise from the positive x axis to the vector. In horizontal axis there is no acceleration, while in the vertical axis there is acceleration due to the gravity. The equations of motion for each axis are WebNow we must find v0y, the component of the initial velocity in the y direction. It is given by v0y = v0sinθ0, where v0 is the initial velocity of 70.0 m/s and θ0 = 75° is the initial angle. Thus, v0y = v0sinθ = (70.0m/s)sin75° = 67.6m/s and y is y = (67.6m/s)2 2(9.80m/s2). Thus, we have y = 233m.

Finding initial velocity

WebThe inital velocity is going to be 'slowed' down to zero (m/s) because of gravity, and the effect will be equally the same returning. Therefore the acceleration/deaccelertion is equl, the distance is equal and so will the time. This will ultimately show that the velocity at the exact same elevation (height) will be the same. WebKinematic equations relate the variables of motion to one another. Each equation contains four variables. The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page describes how this can be done for …
