In frequency modulation the following signals are used 10cos(200Πt) and

10cos(1000Πt). Find the expression of the FM signal, its Bandwidth, modulation

index, the spectral response and the transmitted power. Given, frequency sensitivity is

20 Hz/V

If the body starts from rest at A and slides 200 ft down the 30°

incline, how far will it then move along the other incline? What

will be the velocity when it returns to B? Coeff fr= 0.20.A 100 lb 30° 3 B 200' 4 S

The block slides down an incline. It starts from rest and, after moving 6 ft, strikes a spring (k= 100 lb/in). Determine the maximum deformation of the spring. Coeff fr= 0.20. 600 lb 6' ww 3 4

As shown in figure, find

that at what distance body A

will attain a velocity of 3 m/s

when starts from rest.

Assume coefficient of

friction as 0.2 for block and

surface and pulleys are

frictionless and weightles
