Two airplanes leave an airport at the same
time. the velocity of the first airplane is
650 m/h at a heading of 60.5
◦
. the velocity
of the second is 560 m/h at a heading of 85◦
.
how far apart are they after 2.9 h?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
