Q1. An object (A) of mass 0.2 kg strikes a second object (B) of mass 0.35 kg that is initially at rest. Mass A has an initial velocity of +3m/s.
A) Suppose that the collision is entirely inelastic. Compute the final state for these objects. Calculate the total energy for this system before and after the collision. Is mechanical energy conserved? If not, account for the discrepancy.
B) Now suppose that the collision is now entirely elastic. Calculate and describe the final velocities for two objects A and B. (the collision is in one dimension)
Q2. To monitor the breathing of the hospital patient, a thin belt is girded around the patient's chest as in the figure below. The belt is a 220 turn coil. When the patient inhales, the area encircled by the coil increases by 41 cm2. The magnitude of earth's magnetic field is 50.0 µT and makes an angle of 30° with the plane of the coil. Assume a patient takes 1.50 s to inhale, find the magnitude of average induced emf in the coil during that time.
Heather and Jerry are standing on a bridge 56 above a river. Heather throws a rock straight down with a speed of 15. Jerry, at accurately the same instant of time, throws a rock straight up with the equal speed. Overlook air resistance.
A ball on the porch rolls 60 {rm cm} to the porch's edge, drops 40 {rm cm}, continues rolling on the grass, and eventually stops 80 {rm cm} from the porch's edge.
Obtain a relation between the equilibrium lattice distance

Write down a function named as kineticEnergy() which determines the kinetic energy of an object in accordance with the following formula.
A train is travelling up a 4.0 incline at the speed of 3.25 when the last car breaks free and begins to coast without friction. How long does it take for the last car to come to rest momentarily.
An electric field of 8.55x10^5 V/m is desired between two parallel plates, each of area 35.00 cm^2 and separated by 2.45mm of air. What charge should be on each plate.
A converging lens has a focal length of f = 22.0 cm. An object is placed 41.0 cm from the lens. Find the size of the image in cm if the object has a height of 4 cm. express answer with one decimal place.
Throughout three hours one winter afternoon, when outside temperature was 9° C, a house heated by electricity was kept at 21° C with the expenditure of 46kwh (kilowatt•hours) of electric energy.
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 second baseman tosses the ball to first baseman, which catches it at the same level from which it was thrown. The throw is made with an initial speed of 15 m/s at an angle of 38.0^circ above the horizontal. What is the horizontal component of ba..
A cube of ice is taken from the freezer at -8.0 and placed in a 113 aluminium calorimeter filled with 306 of water at room temperature of 20.0. The final situation is observed to be all water at 15.0.
