A cannon of mass 1400 kg fires a cannon ball of mass 70 kg at a speed of 60 m/s. Calculate the velocity of the cannon, both magnitude and direction.

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?

Two trains leave a station at the same time, train a travels at a constant speed of 16 m/s. train b starts at 8.0 m/s but accelerates constantly at 1.0 m/s squared. after 10.0 seconds, which train has the greater speed?

What is the magnitude of the gravitational force acting on the earth due to the sun?
