height=200 m
speed=500m/s
let they stand x m from plane
time taken to travel 200 m down
200=0.5*9.8*t^2
t=6.39 sec
during this time horizontal distance travelled=x=500*6.39=3194.4 m
time taken=6.39 sec
horizontal component of velocity=500 m/s
vertical component=9.8*6.39=62.62 m/s downwards
plane will be just above the hikers when packet reaches the hiker as speed of plane is also 500 m/s while of packet is also 500 m/s horizontally
How for an advance horizontal distance should the package be dropped in order to reach the...
(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...

A rescue helicopter drops a 10 kg package of emergency supplies to hikers stranded in the rocky valley. The chopper velocity has horizontal component due east at 1 m/s and a vertical component 2 m/s. The pilot drops the package from a height of 30 m above the ground. The acceleration due to gravity is 9.81 m/s2. Where does the package strike the ground relative to the point where it was released? What is the kinetic energy of the package...
A projectile is fired at an angle such that the vertical component of its velocity and the horizontal component of its velocity are both equal to 15 m/s. (a) How long does it take for the ball to reach its high point? (b) What is the vertical distance at this time? (c) What is the horizontal distance at this time? Use g = 10 m/s

A package is dropped from the plane which is flying with a constant horizontal velocity of vA = 200 ft/s. Suppose that h = 1550 ft . (Figure 1) Part A Determine the normal component of acceleration at the moment the package is released at A, where it has a horizontal velocity of v4 = 200 ft/s Express your answer to three significant figures and include the appropriate units. µA Value Units (an)A = Request Answer Submit Figure 1 of...
A small ball (ball 1) is released from rest; i.e. dropped, at the origin (0,0) and falls freely. At the same time another ball (ball 2) leaves the same position with an initial horizontal velocity of 2.70 m/s. Calculate the time it takes ball 1 to fall 3.50 m. What is the time it takes ball 2 to fall 3.50 m? Calculate the horizontal distance ball 2 will move during this time. Calculate the vertical component of the velocity of...

Express your answer with the appropriate units.
Enhanced EOC: Problem 7.31 Two packages at UPS start sliding down the 20 degree ramp shown in the figure. Package A has a mass of 6.50kg and a coefficient of kinetic friction of 0.220. Package B has a mass of 11.5kg and a coefficient of kinetic friction of 0.150. (Figure 1) How long does it take package A to reach the...
the plane is travelling horizontally with a speed of 70.0 m/s, how far in advance of the recipients (horizontal distance) must the goods be dropped? 1. A rescue plane wants to drop supplies to isolated mountain climbers on a rocky ridge 235 m below. If υ,ο Dropped (υ,0 -0) 235 m 5. Vector , is 10.0 units long and points along the negative x axis. Vector 2 is 50.0 units long and points at +75 to the positivex axis. (a)...
A cargo helicopter, descending steadily at a speed of 3.3 m/s, releases a small package. Let upward be the positive direction for this problem. (a) If the package is 31 m above the ground when it is dropped, how long does it take for the package to reach the ground? s (b) What is its velocity just before it lands? (Indicate the direction with the sign of your answer.) cm/s
