Q. Two particles are separated by a certain distance. The force of gravitational interaction between them is Fsub 0. Now the separation between the particles is tripled. Find the new force of gravitational interaction Fsub 1. Express your answer in terms of Fsub 0.
Q. In a circus performance, a monkey is strapped to a sled and both are given an initial speed of 5.0 m/s up a 23.0° inclined track. The combined mass of monkey and sled is 20 kg, and the coefficient of kinetic friction between sled and incline is 0.20. How far up the incline do the monkey and sled move?
Air at 1 ATM & 80 °C is fed to a chiller. The air contains water vapour at 15 degrees of superheat. The air stream is chilled to condense 50% of the water in the feed. At what temperature must the chiller operate if the product streams are also at..
A football is thrown toward a receiver with an initial speed of 20 m/s at an angle of 30.0o above the horizontal. At that instant, receiver is 20 m from the quarterback. In what direction and with what constant speed must the receiver run in order..
An uncharged capacitor is connected to a 55 V battery until it is fully charged, after which it is disconnected from the battery. A slab of paraffin is then inserted between the plates.

You are to gracefully crawl in the tube and sit calmly in seat without holding on to anything. The cannon will then be raised to an angle such that your speed through the air at your highest point is 10 ft/sec.
A series of small machine components being moved by a conveyor belt passes over a 140-mm-radius idler pulley. At the instant shown, the angular velocity of the idler pulley is 5 rad/s clockwise. If the total acceleration of point B is 2400 mm/s2, wha..

A freight company uses a compressed spring to shoot 1.7 kg packages up a 1m high frictionless ramp into a truck. The spring constant is 241 N/m and the spring is compressed 33 cm.
How to find out the elapsed time
A 1530 kg car is travelling with the speed of 15.0 m/s. What is the magnitude of the horizontal net force that is required to bring the car to the halt in a distance of 40.00 m.
