A 33.0-kg child starting from rest slides down a water slide with a vertical height of 15.0 m. (Neglect friction.) (a) What is the child's speed halfway down the slide's vertical distance?
m/s

(b) What is the child's speed three-fourths of the way down?
m/s

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

More solar radiation is absorbed by earth’s surface than by

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.
