An aircraft flying horizontally at a rate of 95.4 m/s drops a
packet from a height of 1,242 meters. Determine the speed the
package reaches at just the moment before touching the surface.
Consider both speed components.
If a body is dropped from a 401-foot-tall building, determine
the time in seconds it takes to reach the ground. (Free fall) enter
s as a unit of time.

Problem 4:A body is projected downward at an angle of 30° with the horizontal from the top of a building 170 m high. Its initial speed is 40 m/s.a) How long will it take before striking the ground?b) At what angle with the horizontal will the body strike?
1. A rock is dropped from a bridge that is 15 m above the surface of the river. How long does it take for the rock to hit the water? 2. A ball is thrown upward from the edge of the roof of a 20 m tall building with an initial velocity of 15 m/s. a) What is the maximum height reached by the ball? b) How much time does it take for the ball to reach the ground? c)...
A block of mass m = 2 kg slides back and forth on a frictionless
horizontal track. It is attached to a spring with a relaxed length
of L = 3 m and a spring constant k = 8 N/m. The spring is initially
vertical, which is its the relaxed postion but then the block is
pulled d = 3 m to one side
1. By what length is the spring extended? _______m
2. What is the potential energy stored...
An m = 7.57 g bullet is fired into a 259 g block that is initially at rest at the edge of a table of h = 1.00 m height as shown in the figure. The bullet remains in the block, and after the impact the block lands d = 1.85 m from the bottom of the table. How much time does it take the block to reach the ground once it flies off the edge of the table? Submit...
Chapter 03, Problem 35 Chalkboard Video A rocket is fired at a speed of 61.0 m/s from ground level, at an angle of 75.0 above the horizontal. The rocket is fired toward an 47.0-m high wall, which is located 19.0 m away. The rocket attains its launch speed in a negligibly 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? 1 Units Number...
