Homework Answers
u = 170km/ h = 170 × 5/18 = 47.2m/s
h= 370m
X= ut( a=0)
Y = uyt +1/2gt^2 = 0.5 gt^2 (uy=0)
370= 0.5 x 9.8 x t^2
t= 8.68s
X= 47.2 x 8.68 =410.2m
Vx= ux+at( put a=0) = 47.2
Vy= uy+ gt (put uy=0)= 9.8 x 8.68= 85.2
V = ( 47.2^2 + 85.2^2)^1/2= 97.36 m/s

An emergency relief airplane is dropping a care package to
people on a small island. The plane is flying with a velocity of v0
= 176 km/h at an altitude of h = 393 m.
If the package must land on the island, at what horizontal
distance D from the plane to the island should the package be
dropped?
Answer:
2.
What is the magnitude of the final velocity of the package the
instant before it hits the ground?

(Figure 1)A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for the plane to land on, and the only way to deliver the package is by dropping it. The airplane flies horizontally with constant speed of 462 km/hour at an altitude of 575 m. The positive x and y directions are defined in the figure. For all parts, assume that the "island" refers to the...

3) A person wants to drop a package from an airplane to the people below. If the plane is flying horizontally at 120 km/hr and drops the package from 60 m above the flat surface. (Neglect air resistance for parts a) and a) If the person in the airplane wants to have the package land 20m behind the people on the ground, where should the person drop the package. (Clearly define a coordinate system so we understand your answer) b)...

10. A boy throws a ball with an initial velocity of 25 m/s at an angle of 30° above the horizontal. If air resistance is negligible, how high above the projection point is the ball after 2.0s? How long is it in the air, and how far does it go before hitting the ground? 11. A projectile leaves the ground at 150 m/s and reaches a maximum height of 0.57 km. If there...
