Q1. 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.

Q2. A car rests on the slanted ramp leading into car-transporter trailer. The car's brakes and transmissions locks are released; only the cable attached to the car and to the frame of the trailer prevents car from rolling backward off the ramp. If the car's weight is w, find out the tension in the cable and the force with which the ramp pushes on the car tires.

What would be the frequency of the resulting beat : A small turtle moves at a speed of 165 furlongs per fortnight. Find out the speed of the turtle in centimeters per second. Note that 1 furlong = 220 yards and 1 fortnight = 14 days. |

Force that maintains circular motion acting on the puck : An archer puts a 0.54 kg arrow to the bowstring. An average force of 202 N is exerted to draw the string back 1.3 m. suppose that air resistance is negligible. |

What direction does the shortest distance make : 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. |

What is its kinetic energy at a : 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.. |

Find out the tension in the cable and the force : 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. |

What is the force caused by the water on bottom : 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. |

The concorde is primarily made of aluminium : 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 an infinite wire with radius carriesa current i : Consider a large parallel plate capacitor with circular plates of radius R. suppose that the electric field between the plates is increasing. |

The magnitudes of components of ship''s displacement vector : 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.. |

## Find the magnitude of the resulting magnetic fieldA sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere. |

## Find the equivalent resistanceA resistor is in the shape of a cube, with each side of resistance R . Find the equivalent resistance between any two of its adjacent corners. |
