An object is projected straight upwards with an initial velocity U. If T is the time taken to return to the point of projection, H is the maximum height and g is the acceleration due to gravity, derive how to solve for: (a.) time of flight, T, and (b.) the maximum height, H, that the projectile can achieve.

A bomber is flying horizontally over level terrain at a speedof 275 m/s relative to the ground and at an altitude of3.00 km. (a) The bombardier releases one bomb. How fardoes the bomb travel horizontally between its release and itsimpact on the ground? Ignore the effects of air resistance.(b) Firing from the people on the ground suddenly incapacitatesthe bombardier before he can call, “Bombs away!”Consequently, the pilot maintains the plane’s originalcourse, altitude, and speed through a storm of flak. Whereis the plane relative to the bomb’s point of impact when thebomb hits the ground? (c) The plane has a telescopic bombsightset so that the bomb hits the target seen in the sight atthe moment of release. At what angle from the vertical wasthe bombsight set?
Check Your Understanding If the two golf shots in Example 4.9 were bunched at the same speed, which shot would have the greatest range? When we speak of the range of a projectile on level ground, we assume R is very small compared with the circumference of Earth. If, however, the range is large, Earth curves away below the projectile and the acceleration resulting from gravity changes direction along the path. The range is larger than predicted by the range equation given earlier because the projectile has father to fail than it would on level ground, as shown in Figure 4.17, which is based on a drawing in Newton’s Principia. If the initial speed is great enough, the projectile goes into orbit. Earth’s surface drops every 8000 m. In 1 s an object falls 5 m without a resistance. Thus, if an object is given a horizontal velocity of 8000 m/s (or 18,000 mi/hr) near Earth’s surface, it will go into orbit around the planet because, the surface continuously falls away from object Thu is roughly the speed of the Space Shuttle in a low Earth orbit when it was operational, or any satellite in a low Earth orbit. These and other aspects of orbital motion, such as Earth’s rotation, are covered in greater depth in Gravitation. Figure 4.17 Projectile to satellite. In each case shown here, a projectile is launched from a very high tower to avoid air resistance. With increasing initial speed, the range increases and becomes longer than t would be on level ground because Earth curves away beneath its path. With a speed of 8000 m/s, orbit is achieved.

One of the fastest recorded pitches in major-league baseball, thrown by Billy Wagner in 2003, was clocked at 101.0 mi/h (45.1 m/s). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically, in meters, by the time it reached home plate, 60.5 ft. (18.4 m) away? *Must include BIG six list for both x and y directions*
