So if I have a kangaroo on planet Y with a specified gravity of 12m/s^2. If he jumps with an inital velocity of 8m/s, how far would he travel?
Which other kinematic equations do you know? You need to pick one with all the variables in that you know plus the one which you want to find out.jacksonbobby5 said:Well I thought I would use the formula y=Vi(time)+1/2g(time)^2, but I don't have a time, just initial velocity and gravity.
Sounds goot to mejacksonbobby5 said:Well, I also had read about an equation that is y=(Vi^2)/2g but I wasnt sure wether this was a valid equation or a kinematic equation. Any clue?
The equation y=(Vi^2)/2g represents the vertical displacement (y) of an object in free fall, where Vi is the initial velocity and g is the acceleration due to gravity.
This equation is derived from the basic kinematic equation for displacement, y=Vi*t + 1/2*a*t^2, where a is the acceleration. Since the object is in free fall, a is equal to the acceleration due to gravity (g), which is a constant value. By rearranging the equation, we can solve for y and get y=(Vi^2)/2g.
Yes, this equation can be used for objects with any initial velocity (Vi). The equation takes into account the initial velocity and the acceleration due to gravity to calculate the vertical displacement of the object.
This equation is a simplified version of the equation for projectile motion, which takes into account both the horizontal and vertical components of the object's motion. When the object is only moving in the vertical direction, this simplified equation can be used.
The units for y (vertical displacement) and Vi (initial velocity) are meters (m), while the unit for g (acceleration due to gravity) is meters per second squared (m/s^2).
