• An airplane climbs at an angle of 15 degrees with a horizontal
component of speed of 200 km/h. (a) What is the plane's
actual speed? (b) What is the magnitude of the vertical
component of its velocity?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
