B1.5mOne end of a light inextensible string is attached to a particle A of mass 2kg. The other end of thestring is attached to a second particle B of mass 2.5kg. Particle A is in contact with a rough planeinclined at e to the horizontal, where cos e =. The string is taut and passes over a small smoothpulley P at the top of the plane. The part of the string from A to P is parallel to a line of greatestslope of the plane. Particle B hangs freely below Pat a distance 1.5m above horizontal ground, asshown in the diagram.The coefficient of friction between A and the plane is u. The system is released from rest and in thesubsequent motion B hits the ground before A reaches P. The speed of B at the instant that it hitsthe ground is 1.2ms.(a) For the motion before B hits the ground, show that the acceleration of B is 0.48 ms2.(b) For the motion before B hits the ground, show that the tension in the string is 23.3N.(c) Determine the value of u.After B hits the ground, A contimues to travel up the plane before coming to instantaneous restbefore it reaches P.(d) Determine the distance that 4 travels from the instant that B hits the ground until 4 comes toinstantaneous rest.

(a) For the motion before B hits the ground, show that the acceleration of B is 0.48 ms . (b) For the motion before B hits the ground, show that the tension in the string is 23.3N. (c) Detemine the value of u. After B hits the ground, A contimues to travel up the plane before coming to instantaneous rest before it reaches P. (d) Detemine the distance that A travels from the instant that B hits the ground until A comes to instantaneous rest.

The Sultan Qaboos road is designed to operate at a speed of 100Kmph, but some people are racing above the limit and some people are trailing below 80Kmph, and cause multiple incidents on road. Design a radar frequency so that detect the both the speeds that is below 70kmph, and above 110kmph, provided the PRF is 500Hz only. The radar should not be blind between the above specified velocities and it should detect both the speed accurately.(Explain your assumptions of the radar and their specifications clearly, so that which radar frequency can be readily used on site)

Uphill escape ramps are sometimes provided to the side of steep downhill highways for trucks with overheated brakes. For a simple 14 ∘ upward ramp, what length would be needed for a runaway truck traveling 160 km/h ? Note the large size of your calculated length. (If sand is used for the bed of the ramp, its length can be reduced by a factor of about 2.)
