27 ILW A certain airplane has a JITOLO spéed of 290.0 km/h and is diving at an angle of e = 30.0° below the hor- izontal when the pilot releases a radar decoy (Fig. 4-33). The hori- zontal distance between the release (s) oted point and the point where the decoy strikes the ground is d 700 m. (a) How long is the decoy in the air? (b) How high was the release point? boan Fig. 4-33 Problem 27. IRn *28 In Fig. 4-34, a stone is pro- jected at a cliff of height h with an initial speed of 42.0 m/s directed at angle &= 60.0° above the horizontal. The stone strikes at A, 5.50 s after launching. Find (a) the height h of the cliff, (b) the speed of the stone just before impact at A, and (c) the maximum height H reached above the ground.

A dive-bomber has a velocity or 280 m/s at ail angle below the horizontal. When the altitude of the aircraft is 2.15 km, it releases a bomb, which subsequently hits a target on the ground. The magnitude of the displacement from the point of release of the bomb to the target is 3.25 km. Find the angle .

In a football game, a player wants to kick the ball as far as possible, but also make sure that it stays in the air as long as possible, so that there is enough time for other players to run down the field and tackle the receiver. If the football is supposed to travel a distance of 49.8 m and stay in the air for 4.41 s, what initial angle and speed does the player have to provide? You can assume that the initial and final vertical coordinate are zero. Hint: Start from the range equation that you derived in class.

Determine (a) the maximum height reached by the projectile, (b) the total time in the air, (c) the total horizontal distance covered (that is, the range), and (d) the speed of the projectile 1.50 s after firing
A rocket is fired at a speed of 83.0m/s from ground level, at an angle of 66.0 degrees above the horizontal. The rocket is fired towards an 28.8m high wall, which is located 25.0m away. The rocket attains its launch speed in a neglibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall (in meters)?
