A jet with mass m = 1.3 × 105 kg jet accelerates down the runway for takeoff at 2.4 m/s2.
1.Once off the ground, the plane climbs upward for 20 seconds. During this time, the vertical speed increases from zero to 18 m/s, while the horizontal speed increases from 80 m/s to 91 m/s. What is the net horizontal force on the airplane as it climbs upward?
2.What is the net vertical force on the airplane as it climbs upward?
3. After reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 13 seconds. What is the net horizontal force on the airplane as it levels off?
4. What is the net vertical force on the airplane as it levels off?
An infinite non conducting sheet has a surface charge density σ = +5.80 pC/m2. (a) How much work is completed by electric field because of the sheet if a particle of charge q = +1.60 × 10-19 C is moved from the sheet to a point P at distance d = 3.56..
A proton moves perpendicular to a uniform magnetic field, B, at 1.6 multiplied by 107 m/s and experiences an acceleration of 1.8 multiplied by 1013 m/s2 in the positive x direction while its velocity is in the positive z direction. Find out the magni..
How much friction must be exerted between the skates and ice.
A second fragment, who's mass is 3.4 kg, moves away from the point of explosion with a speed of 418 m/s along the negative x axis. What is the speed of the third fragment? Ignore effects due to gravity.
The cockroach's speed (relative to the ground) is 2.0 m/s, and the lazy Susan turns clockwise with angular velocity ω0 = 3.2 rad/s. The cockroach find out a bread crumb on the rim and, of course, stops.
The rope makes an angle of 70.0 degrees with respect to the vertical as shown. Illustrate what is the tangential speed of the ball?
An aluminum wire with a diameter of 0.105 mm has a uniform electric field of 0.295 V/m imposed along its entire length, What is the drift speed of the conduction electrons
A large wooden turntable in the shape of the flat disk has a radius of 2.00 {rm m} and a total mass of 120 {rm kg}. The turntable is initially rotating at 3 {rm rad}/{rm s} about a vertical axis through its center.
A jogger travels a route that has two parts. The first is a displacement of 2.70 km due south, and the second involves a displacement that points due east.
In a head-on collision, the car stops in 0.279 from a speed of 16. The driver has a mass of 68, and is, fortunately, tightly strapped into his seat. What force is applied to the driver by his seat belt during that fraction of a second.
Monochromatic light ( = 630 nm) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.20 m from the slits. It shows the interference pattern observed on the screen. What is the slit separatio..
Identical point charges of +3.6 C are fixed to diagonally opposite corners of a square. A third charge is then fixed at the center of the square, such that it causes the potentials at the empty corners to change signs without changing magnitudes.
