A plane took 3.55 hours to finish a journey. If the distance of the journey was 2840 miles, at what average speed did the
plane travel?
mph

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

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.

The ability to make things happen is also called a. heat b. force c. matter d. energy
