A ball is thrown forward at 5 m/s. How would the path of the ball differ on Earth than on the moon? The ball would follow a curved path on Earth but a straight path on the moon. The ball would follow the same curved path on Earth as on the moon. The ball would curve down more sharply on Earth than on the moon. The ball would curve down on Earth but curve up on the moon.

Which notation is used to represent an alpha particle? a. b. c. d.

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.
