i am not sure but i can give u the expression for the speed at periapsis, Vp2 = 2μ{ 1/r1 - 1/(r1+ r2 )}.

To calculate the periapsis, you need to know the initial velocity and distance relative to a central body. The periapsis is the point of closest distance in an orbit. One way to calculate it is by using the specific orbital energy equation, which is the sum of the gravitational potential energy and the kinetic energy: ε = -(GM) / (2a), where ε is the specific orbital energy, G is the gravitational constant, M is the mass of the central body, and a is the semi-major axis of the orbit. The periapsis can then be determined by subtracting the distance relative to the central body from the semi-major axis.

How do you calculate acceleration when given velocity and distance?
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
What formula is used to calculate velocity?
v=d/t where d is the distance and t is the time
How do you calculate acceleration from velocity?
There are 3 formula 1. Final velocity = starting velocity + (acceleration)(time) 2. Final velocity^2 = starting velocity^2 + 2(acceleration)(distance) 3. Distance = (starting velocity)(time) + 1/2(acceleration)(time^2) Use whichever you can use.
I understand distance divided by time is the formula to calculate work How can I show an example to apply the formula?
Work is not defined as distance/time, but rather: work= force x distance Distance divided by time will give you velocity. Displacement (or distance traveled) = velocity x time
How do you calculate tota distance traveled when given velocity time and acceleration?
Assuming constant acceleration: distance = v(0) t + (1/2) a t squared Where v(0) is the initial velocity.
How do calculate the velocity of the boat relative to the shore?
Add the rivers velocity to the boats velocity
How do you calculate acceleration from distance and time?
Acceleration= Distance/time (distance divided by time) That's the dumbest answer I've ever heard.. Acceleration = Final Velocity - Initial Velocity/Time Velocity = Displacement/Time So you can't calculate acceleration from distance and time, you can only do velocity.
Is it possible to calculate distance when given velocity and weight?
yes...
What two measurements would you use to calculate the velocity of an object?
To calculate the velocity of an object, you would typically need two measurements: the distance traveled and the time taken to travel that distance. By dividing the distance traveled by the time taken, you can determine the object's velocity.
To find the acceleration of an object moving in a straight line you must calculate the charge in distance during unit of time?
To find the acceleration of an object moving in a straight line, you must calculate the change in velocity during a unit of time. Acceleration is the rate of change of velocity over time, not distance. It is given by the formula acceleration = (final velocity - initial velocity) / time.
How do you calculate the velocity of the boat relative to shore?
To calculate the velocity of the boat relative to the shore, you would subtract the velocity of the shore from the velocity of the boat. This difference will give you the boat's speed and direction with respect to the shore.
How do you calculate distance when given velocity and weight?
To calculate distance with velocity and weight, you can use the equation for work: Work = Force x Distance. The force can be calculated by multiplying the weight with gravity. Velocity can then be used to determine the time it takes for the object to travel that distance using the equation Distance = Velocity x Time.
A river current has a velocity of 5 kmh relative to the shore. A boat moves in the same direction as the current at 4 kmh relative to the river. How do you calculate the velocity of the boat relative?
The velocity of the boat relative to the shore is the vector sum of its velocity relative to the river and the velocity of the river current. In this case, it would be 4 km/h (boat's speed) + 5 km/h (current's speed), which equals 9 km/h.
How do you calculate acceleration when given velocity and distance?
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
How do you calculate height based on velocity and time?
I assume you refer to the formula distance = velocity x time. If an object moves upward, the distance would become the height.
Is it true that to calculate acceleraltion you need to know both the final and the initial velocity of an object?
No. That's only one of several possibilities. -- with initial velocity, distance, and time, you can calculate acceleration -- with final velocity, distance, and time, you can calculate acceleration -- with force and mass, you can calculate acceleration -- with initial and final momentum, you can calculate acceleration -- with initial and final kinetic energy, you can calculate acceleration -- with mass, velocity at either end, and kinetic energy at the other end, you can calculate acceleration And I'm sure there are several more that I've missed.
What two measurements must be known to calculate velocity?
To calculate velocity, you need to know both the object's displacement (change in position) and the time it takes for that displacement to occur. Velocity is the rate of change of position with respect to time.
