Agolfer hits a golf ball with an initial velocity of 140 ft/s at an angle of 25° with the horizontal. knowing that the fairway slopes downward at an average angle of 5°, determine the distance d between the golfer and point b where the ball first lands.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

conservation of mass

mass before something happens = mass afterwards

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
