36. A rifle is used to shoot twice at a target, using identical cartridges.The first time, the rifle is aimed parallel to the ground and directly at thecenter of the bull's-eye. The bullet strikes the target at a distance of H,below the center, however. The second time, the rifle is similarly aimed,but from twice the distance from the target. This time the bullet strikesthe target at a distance of H3 below the center. Find the ratio H„/H,.

The horizontal displacement can be expressed as, x=v0xtt=xv0x The vertical displacement can be…

You fly 32.0 km in a straight line in still air in the direction 35.0° south of west. (a) Find the distances you would have to fly straight south and then straight west to arrive at the same point. (This determination is equivalent to finding the components of the displacement along the south and west directions.) (b) Find the distances you would have to fly first in a direction 45.0° south of west and then in a direction 45.0° west of north. These are the components of the displacement along a different set of axes—one rotated 450°.
Figure P3.28 illustrates typical proportions of male (m) and female (f) anatomies. The displacements d1m and d1f from the soles of the feet to the navel have magnitudes of 104 cm and 64.0 cm. respectively. The displacements d2m and d2f from the navel to outstretched fingertips have magnitudes of 100 cm and 86.0 cm, respectively. Find the vector sum of these displacements d3=d1+d2 for both people.

A rocket is launched at an angle of 53.0 above the horizontal with an initial speed of 100. m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. Find (a) the maximum altitude reached by the rocket, (b) its total time of flight, and (c) its horizontal range.
An enemy ship is on the east side of a mountain island, as shown in the figure. The enemy ship has maneuvered to within d1 = 2077 m of the h = 1940 m high mountain peak and can shoot projectiles with an initial speed of vi = 244 m/s. If the western shoreline is horizontally d2 = 273 m from the peak, what are the distances from the western shore at which a ship can be safe from the bombardment of the enemy ship?

1.1 An aircraft flies on a 110° course at a constant speed of 525 km/h. If the wind speed vector is from 40 km/h to 210°, what is the aircraft's speed vector? (Shows the diagram of velocity vectors with respect to the North.)
In the Superbowl, a quarterback throws a football while standing at the very center of the field on the 50 yard line. The ball leaves his hand at a height of 5 ft and has initial velocity of ~v(0) =< 40, 35, 32 > ft/sec. Assume an acceleration of 32 ft/sec2 due to gravity, i.e., ~a(t) =< 0, 0, −32 >, and that the vector ~i points down fieldtoward the endzone and that the vector ~j points to the sideline. The field is 150 ft in width and 300 ft in length.(a) Determine the position function that gives the position of the ball t seconds after it isthrown. (b) The ball is caught by a player 5 ft above the ground. Is the player in bounds or out ofbounds when he receives the ball? (Assume the player is standing vertically with bothtoes on the ground at the time of reception.)
