What is orthogonal trajectories?
Two curves which intersect at right angles, ( the angle between the two tangents to the curve) curves at the point of intersection are called orthogonal trajectories. The product of the slopes of the two tangents is -1.
If two angles are vertical then what are they?
If two angles are vertical then they are congruent.
How do you find final velocity given mass of both objects and there initial velocities and one of their final velocities?
Suppose the two masses are m1 and m2. Their initial velocities are u1 and u2 and final velocities are v1 and v2. Then, using conservation of momentum. m1*u1 + m2*u2 = m1*v1 + m2*v2 Both m1 and m2 are given. Their initial velocities u1 and u2 are given and one of the two final velocities v1 and v2 is given which leaves only one unknown. So substitute all those values and calculate away.
What Vertical Angles Mean?
When two angles are opposite each other. For example in an "X" the two side openings are vertical and the bottom and top angles are vertical
How do you caluate acceleration?
You first subtract two velocities at two different time intervals. This gives you a difference of velocity. Then you divide this by the time.
