You are standing at an observation point on the ground, when you see an eagle flying...
1. An airplane if flying horizontally at a constant height of 6 km above a fixed observation point. At a certain moment the angle of elevation θ is 30° and decreasing and the speed of the plane is 4 km/h. (a) How fast is 0 decreasing at this moment? (b) How fast is the distance between the plane and the observation point is changing at this moment? 2. Trajectory of a particle is described by parametrical equations as t,y P,...
An airplane is flying with a velocity of 97.0 m/s at an angle of 22.0 ∘ above the horizontal. When the plane is a distance 126 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will the suitcase land? You can ignore air resistance.
An airplane is flying with a velocity of 85.0 m/s at an angle of 19.0 ∘ above the horizontal. When the plane is a distance 114 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will the suitcase land? You can ignore air resistance.
1. 2. Numerical Problems An aeroplane is flying horizontally at a speed of 100 m's releases a bomb at a height of 500 m. Find (1) the time taken by the to reach the ground. (ii) The horizontal distance where the bomb strikes the ground A bomb is dropped from an aeroplane when it is directly above a target at a height of 1500 m. If the speed of the aeroplane in the horizontal direction is be 540 km/h, calculate...
An airplane is flying with a velocity of 99.0 m/s at an angle of 22.0 degree above the horizontal. When the plane is a distance 109 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog with suitcase land? You can ignore air resistance.
A cannonball is fired from the ground and lands on a hill as shown in the figure below: 35° 150 m The initial velocity of the cannonball as it exits the canon is 50 m/s and it is launched at an angle of 35 above the horizontal. The cannonball lands on the hillside 150 m away from the cannon in the horizontal direction (as shown). 2 pts - a) What are the x- and y-components of the initial velocity of...
7. An elevation difference measurement by a total station is (a) is from the ground point at the total station to the ground point at the prism computed from only slope distance and zenith angle (b) requires the horizontal circle to compute the elevation difference (c) requires sighting a known elevation on a backsight (d) usually requires height of instrument and height of target to be correctly derived 8. A horizontal angle at 2 from 1 to 3 is 65-08-10,...
A man is standing on a ledge when he throws a ball. The speed of the ball when released from his hand is 20.0 m/s . The ball is 45.0 m above the ground when released from the man's hand. On the ground below, a boy begins running away from a point directly below the man on the ledge at a constant speed of 6.00 m/s. The boy runs in a straight line along the ground. As the boy runs,...
VA+VB 2. You are flying a kite and get the kite stuck in a tree at a height of 10.0 m above the ground. You stand on the ground 5.0 m horizontal distance from point on the ground below the kite, and throw a rock at the kite, hoping to dislodge it. If you release the rock at a height of 2.0 m above the ground, at an angle of 70 degrees above the horizontal, what speed does the rock...
A helicopter is flying in a straight line over a level field at a constant speed of 5.70 m/s and at a constant altitude of 8.90 m. A package is ejected horizontally from the helicopter with an initial velocity of 14.0 m/s relative to the helicopter and in a direction opposite the helicopter's motion, Find the initial speed of the package relative to the ground, What is the horizontal distance between the helicopter and the package at the instant the...
