u (Initial velocity) = ? Solve the two equations (\sqrt{3}/2)v t = 20 and -4.9t^2+. v = 35.3 m/s. As soon as you stop, the final velocity is zero. In this equation, [latex]\text{u}[/latex] stands for initial velocity magnitude and [latex]\small{\theta}[/latex] refers to projectile angle. Answer: The initial velocity can be found using the formula: v i = v f - at. To create this article, 9 people, some anonymous, worked to edit and improve it over time. The basic definition of average velocity is: Vavg = Δx/Δt = Xf – X0/tf – t0 This is the change in position divided by the time of travel. Compute his initial velocity? (2) If final velocity, acceleration, and distance are provided we make use of: (3) If distance, acceleration and time are provided. Find an object's initial velocity using the appropriate formula for the information you have available: u = v-at, or u^2 = v^2-2as, or u = s/t-1/2at. Find the initial velocity of that object. A bullet of 60 gm is fired using a rifle of mass 12kg. What is the initial velocity? How can I get the final velocity without the initial velocity? Multiply the acceleration by the distance and the number two. Required fields are marked *. Learn more... Velocity is a function of time and defined by both a magnitude and a direction. Rifle recoils with a velocity of 2.5m/s. If you are asking about the initial speed of a falling object (in a vacuum) then you use the formula: s=ut+1/2gt² where s is the distance, u is the initial velocity, t is the time, and g … Include your email address to get a message when this question is answered. For example: An object accelerating west at 7 meters (23.0 ft) per second squared traveled a distance of 150 meters (492.1 ft) within 30 seconds. Distance s = 100m Final velocity = V f = V i + at. By using our site, you agree to our. To create this article, 9 people, some anonymous, worked to edit and improve it over time. Projectile motion calculator solving for initial velocity given range, projection angle and gravity ... Change Equation Select to solve for a different unknown vertical velocity. What will be the height of an object with an initial velocity of 6 f/s and an initial height of 13 ft after 2.5 secs? Q. A race car starts at rest and speeds up uniformly to the right until it reaches a maximum velocity of 60m/s in 15 sec. v i = +4.90 m/s. t (Time taken) = 3 s We multiply both sides by the initial velocity squared v o 2: (v o 2)(1) = (v o 2)(cos 2 θ) + (v o 2)(sin 2 θ) v o 2 = (v o cosθ) 2 + (v o sinθ) 2.
