The 20 kg suitcase A is released from rest at point C of height 3 m from floor ED. The suitcase slides down a friction-less ramp between C and E and continues sliding on the floor until stopping at a certain distance from E.
The coefficient of friction between the floor ED and suitcase A is µ(ED) = 0.4.
Consider g = 9.8 m/s2
Calculate the distance in m from point E reached by suitcase A as it stops.
The figure shows two inter-connected hydraulic cylinders (Cylinder 1 and Cylinder 2), which working chambers are filled with oil (incompressible fluid).
The diameter of Cylinder 1 is given as 45 mm.
The diameter of Cylinder 2 is given as 150 mm.
The diameter of the piston push rod is given as 30 mm.
Q: Calculate the displacement of the piston of Cylinder 2 according to the coordinate system shown in the figure and as a result of the piston of Cylinder 1 being pushed by a distance d = 100 mm as shown in the figure.
Give your answer in meters.
A supply of pressure is connected to the working chamber of Cylinder 2, delivering a pressure P2 of 4 bar.
The diameter of Cylinder 2 is given as 150 mm.
The diameter of the piston push rod is given as 30 mm.
Q: Calculate the x component value of the vector force F2 produced onto the piston by pressure P2 in the cylinder, according to the coordinate system shown in the figure.
Give your answer in Newtons.

write a program that inputs temperature from the user and show a message according to following condition

between 15 to 25 show cool day
between 26 to 35 show pleasent day
grater than 35 show hot day
A pendulum has max displacement of A=2.5m and frequency=6Hz. Displacement at time x is x=Asin(wt).where A is max displacement and w is angular velocity 2pief.
Find time when displacement is 90cm.

Using a Power series expansion of above equation verify a time of 0.0416seconds for displacement to reach 250cm
A diffraction grating is used to resolve two yellow lines 5770 Å and 5790 Å in the 3rd order. If the grating element () is 0.35 mm, calculate the angular location of 3rd order yellow line with respect to the normal. Determine the total width of the ruling/ruled surface.
A plane diffraction grating is illuminated with a monochromatic light of wavelength 5100 Å. If the angle of diffraction for third order maxima is 22.5o, calculate the number of lines in one inch of the grating surface. Also, if this grating is illuminated with another light of wavelength 5200 Å, then find the angle of separation of 5100 Å and 5200 Å lines in second order spectrum.
