4 Ways to Find Initial Velocity - wikiHow

WebSep 16, 2024 · If you are given the final velocity, acceleration, and distance, you can use the following equation: Initial velocity: Vi = √ [Vf2 - (2 * a * d)] Understand what each symbol stands for. Vi stands for “initial velocity”. Vf stands for “final velocity”. a stands for “acceleration”. d stands for “distance”. 2. WebApr 7, 2024 · Question: If a 2000kg satellite orbits around the earth at the height of 300km, what is the speed of the satellite and its period? Answer: The orbital speed is independent of the mass of the satellite if the mass is much less than that of the Earth so. The equation for orbital velocity is v = Square Root (GM / r) Where v is the linear velocity WebYou actually don’t need the mass to solve for speed. For example, we can leave T in terms of mass (m), so that T = m*9.8 / cos30. Then, plugging this T into the derived equation for v [v = sqroot (Tsin30*Lsin30) / m], you get v = sqroot (m*9.8*sin30*Lsin30 / m*cos30). There is an m in the numerator and the m in the denominator, so they cancel. sheriff bot
