Luke stands on a scale in an elevator which has a constant acceleration upward. The scale reads 0.964 kN. When Luke picks up a box of mass 18.2 kg, the scale reads 1.202 kN. (The acceleration remains the same.) Calculate the acceleration of the elevator (enter first). Is it up...

A model sailboat is slowly sailing west across a pond at 0.342 m/s. A gust of wind blowing at 28.7° south of west gives the sailboat a constant acceleration of magnitude 0.305 m/s2 during a time interval of 1.87 s. If the net force on the sailboat during the 1.87-s interva...

A gull is flying horizontally 8.17 m above the ground at 6.35 m/s. The bird is carrying a clam in its beak and plans to crack the clamshell by dropping it on some rocks below. Ignoring air resistance, what is the horizontal distance to the rocks at the moment that the gull sho...
