A body is projected with an initial upward velocity component of 80ms and horizontal veocity component of 100ms. -find the position and velocity of the body after 3s
-how long a time is required to reach the highest point of trajectory
-how high is this point
-time required for thr ball to return to its original level​

The plum pudding model of the atom states that ?

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

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.
