In the figure here, a ball is thrown up onto a roof, landing 4.20 s later at height h=20.0 m above the release level. The ball's path just before landing is angled at 0= 54.0° with the roof. (a) Find the horizontal distance d it travels. (Hint: One way is to reverse the motion, as if it is on a video.) What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's initial velocity? Ꮎ

Jse the worked example above to help you solve this problem. An Alaskan rescue plane drops a package of emergency rations to stranded hikers, as shown in the figure. The plane is traveling horizontally at 45.0 m/s at a height of 1.40 x 104 m above the ground. (a) Where does the package strike the ground relative to the point at which it was released? 241 (b) What are the horizontal and vertical components of the velocity of the package just before it hits the ground? horizontal 45 m/s 52.3832 vertical The response you submitted has the wrong sign. m/s (c) Find the angle of the impact. 49 The response you submitted has the wrong sign.°

In the figure, a ball is thrown leftward from the left edge of the roof, at height h above the ground. The ball hits the ground 1.60 s later, at distance d = 26.0 m from the building and at angle 0 = 67.0° with the horizontal. (a) Find h. (Hint: One way is to reverse the motion, as if on videotape.) What are the (b) magnitude and (c) angle relative to the horizontal of the velocity at which the ball is thrown (positive angle for above horizontal, negative for below)?
