A 5.2 x10^2-newton girl takes 10. Seconds to run up two flights of stairs to a landing, a total of 5.0 meters vertically above her starting point. What power does the girl develop during her run.
A 1040 kg car carrying four 80 kg people travels over a rough "washboard" dirt road with corrugations 2.0 m apart that causes the car to bounce on its spring suspension. The car bounces with maximum amplitude as its speed is 21 km/h. The car now stop..
A 37-kg girl is bouncing on a trampoline. All through a certain interval after she leaves the surface of the trampoline, her kinetic energy decreases to 215 J from 430 J. How high does she rise during this interval? Avoid air resistance.
An 84 kg skier is being pulled by a boat with a force of 240 N causing the skier to accelerate at 1.4 m/s^2. Find out the drag force on the skier.
An aluminium cup of 180 cm3 capacities is totally filled with glycerin at 18° C. How much glycerin (in cubic cm) would spill out of the cup if temperature of both the cup and glycerin is increased to 33° C? (The linear expansion coefficient of alumin..
Consider a large parallel plate capacitor with circular plates of radius R. suppose that the electric field between the plates is increasing.
A hollow aluminium cylinder is to be fitted over a steel piston. At 22°C the inside diameter of the cylinder is 99.2 percent of the outside diameter of the piston. To what common temperature must the two pieces be heated in order that the cylinder ju..
An electric force of 4.0 N exists between two objects separated from each other by a distance of r. If the distance is decreased to 0.50 r, compute the magnitude of the force between the two objects.
