Q. A humanitarian aid package is dropped from a plane flying horizontally 500m above the ground with a speed 100m/s. What is the speed of the package at time of impact? (Calculate the total speed, not a horizontal or vertical projection.)
Q. An 88 g arrow is fired from a bow whose strength exerts an average force of 110 N on the arrow over a distance of 78 cm. What is the speed of the arrow as it leaves bow?
A production line inspector wants a mirror that produces an upright image within magnification of 7.4 when it is located 15 mm from a machine part.
A plane diving with constant speed at an angle of 51.7° with the vertical, releases a package at an altitude of 437 m. The package hits the ground 2.93 s after release. How far horizontally does the package travel.
The parallel metal plate of a capacitor is detached by a distance of 0.5cm and is connected to a 90v battery. Find the electric field between them and surface charge density on the plate.
A parallel-plate capacitor is formed from two 4 electrodes spaced 1.20 mm apart. The electric field strength inside the capacitor is 1.29x 10^6. What is the charge (in nC) on each electrode.
A particular nucleus of the element plutonium contains 94 protons and 150 neutrons. What is the magnitude of the force from the nucleus on a single electron that is at a distance of 0.563 × 10-12 m from the plutonium nucleus.
A cable is used to raise a 29kg urn from an underwater archeological site. There is a 21 N drag force from the water as the urn is raised at a constant speed.

A parallel beam of light from a He-Ne laser, with wavelength of 644 nm, falls on two very narrow slits 0.05 mm apart. How far apart are the fringes in the center of the pattern on a screen 2.2m away.
A stone is dropped at t = 0. A second stone, with 2 times the mass of the first, is dropped from same point at t = 190 ms. (a) How far below the release point is the center of mass of two stones at t = 390 ms? (Neither stone has yet reached the gr..
In daily life we see many cases of people who are caught misrepresenting things and who soon after that are excused and accepted by their contemporaries. How is this different in science.
A 3.60-{rm m}-long, 430 {rm kg} steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 66.0 {rm kg} construction worker stands at the far end of the beam. What is the magnitude..
