Abody falling freely from a given height h hits an inclined plane in its path at a height h. as a result of impact, the direction of the velocity of the body become 30 degree with horizontal axis. for what value of h/h the body will take max time to reach the ground. also find its maximum velocity before striking the ground.

Select the word from the list that best fits the definition classification of most stars on the h-r diagram

You are given two vectors a⃗ =−3.00ι^ 5.00j^ and b⃗ =5.00ι^ 2.00j^. let the counterclockwise angles be positive.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
