How to find the initial velocity given only angle and distance …
2010年9月19日 · An object is shot (from a cannon) at an angle of 33 degrees and landed 85 m away. Calculate the magnitude of the initial velocity (Hint:Look at the x direction and solve for Vox) Homework Equations Other questions I must answer. If you have time, help with these would be great, however I think if I can just find the initial velocity I should be ...
Solving for distance using only initial velocity and coefficient of ...
2008年11月24日 · At the early point (probably around chapter 4) of an "elementary physics" textbook, a student encounters problems where, given an initial velocity and coefficient of friction, the student is expected to provide the resulting final displacement. This is a stage of the textbook where kinetic energy equations and "work" equations have not yet been ...
Find Initial Velocity (With Wind Factored In) - Physics Forums
2010年2月16日 · FAQ: Find Initial Velocity (With Wind Factored In) What is initial velocity and why is it important to factor in wind? Initial velocity is the speed at which an object is launched or thrown. It is important to factor in wind because wind can affect the trajectory and speed of an object, thus impacting its final position and landing point.
How to find initial velocity given distance and angle - Physics Forums
2014年1月14日 · To find the initial velocity given distance and angle, you can use the following formula: V 0 = √(g*d/sin(2θ)), where g is the acceleration due to gravity (usually 9.8 m/s^2), d is the distance traveled, and θ is the launch angle.
How Do You Calculate Rocket Initial Velocity Using ... - Physics …
2009年6月9日 · The initial velocity of a rocket is important because it determines the trajectory and flight path of the rocket. It also impacts the amount of fuel and thrust needed for the rocket to reach its desired destination. Can the initial velocity of a rocket be changed? Yes, the initial velocity of a rocket can be changed by adjusting the amount of ...
Initial velocity given time and angle - Physics Forums
2020年1月28日 · From Ball 1 I can can determine it's initial velocity and then maximum height. I'm not sure how this is relevant, as I cannot find a formula using angle, time, height and velocity. I have found h=V(squared) x sin (squared) Theta / 2g …
Can I find time without knowing initial velocity? - Physics Forums
2012年5月19日 · 1. My problem is I know displacement is 20m, acceleration is -5.4m/s, final velocity is 0m/s, coefficient of friction=0.55, the object slowing down weighs 1000kg, can I find initial velocity and the time it took to slow down and if so how? I have no idea how to go about this problem 2. Equations...

2007年10月18日 · A ball is pictched at a batter, the batter hits the ball at a 45 degree angle It just clears the outfield fence 98m away Find velocity of the ball when it left the bat. Assume fence is the same height as the pitch. Disreguarding air friction I can't figure out how to find initial velocity.
Projectile: Find initial velocity without time - Physics Forums
2010年9月11日 · To find initial velocity without time, we need to know the initial height of the projectile, its final height, and the distance it travels horizontally. 5. What is the formula for finding initial velocity without time? The formula for finding initial velocity without time is: V 0 = √(2gh + d x), where V 0 is the initial velocity, g is the ...
