Q. A golf ball rolls off a horizontal cliff with an initial speed of 13.9 m/s. The ball falls a vertical distance of 15.0 m into a lake below.
(a) How much time does the ball spend in the air?
(b) What is the speed v of the ball just before it strikes the water?
An airplane with a speed of 33 m/s is climbing upward at an angle of 52° with respect to the horizontal. When the plane's altitude is 540 m, the pilot releases a package.
(a) Calculate the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth.
(b) Relative to the ground determine the angle of the velocity vector of the package just before impact. Clockwise from the positive x axis.
You then maintain a constant speed of 65.0 mph. You pass the patrol car 16 seconds after you at first applied the brakes and are relieved that he doesn't pull out after you. How far away was the highway patrol car when you first saw it.

A spaceship is coming directly toward you while you are in the international space station. You are told that the spaceship is shining sodium light. You have an apparatus that and resolve two closely spaced wavelengths if the difference is 0.55 nm. I..
An air molecule is moving at a velocity of 444 m/s. How various meters would the molecule move during 7.00 ms (milliseconds) if it didn't collide with any other molecules.
A car is parked on a steep incline, making an angle of 37.0° below the horizontal and overlooking the ocean, when its brakes fail and it begins to roll. Starting from rest at t = 0, the car rolls down the incline with a constant acceleration of 3...
You're carrying a 3.6-m-long, 25kg pole to a construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35cm from its tip.
If astronauts could travel at v = 0.950 c, we on Earth would say it takes (4.20 / 0.970) = 4.42 years to reach Alpha Centauri, 4.20 light-years away. The astronauts disagree. How much time passes on astronauts' clocks? What is the distance to Alph..
A 40-kg girl is bouncing on a trampoline. During a certain interval after leaving the surface of the trampoline, kinetic energy decreases to 240J from 470J. How high does she rise during this interval? Avoid air resistance.
