A weight A with mass m = 18 kg is attached to the free end of a nonlinear spring such that the acceleration of A is a = g − (m γ ) (y − L 0 ) 3, where g is the acceleration due to gravity, γ is a constant, and L 0 = 0.55 m. Determine γ such that A does not fall below y = 1 m when released from rest at y = L 0. The vatue of y is kg 2 m 2

If the air-fuel ratio (A/F) is 18 kg air/kg fuel, determine the percentage of theoretical air used during this process. Draw a simple block diagram for the combustion chamber of the jet engine as a control volume, clearly showing the control surface and the input reactants and the output products (without O2) simple with arrows.

The (Figure 1) shows three masses. Take m 1 = 32 kg, m 2 = 5.0 kg, and m 3 = 18 kg. For help with math skills, you may want to review: Vector Addition Determining the Angle of a Vector What is the magnitude and direction of the net gravitational force on the mass m 1 ? Enter the magnitude and direction of the net force separated by a comma.

Question: Two children of mass 18 kg and 29 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. If the children are separated by a distance of 5 m, at what distance from the pivot point is the small child sitting in order to maintain the balance?

Use the Köhler curves shown below to estimate: (a) The radius of the droplet that will form on a sodium chloride particle of mass (b) The relative humidity of the air adjacent to a droplet of radius 0.04 μm which (c) The critical supersaturation required for an ammonium sulfate particle of mass 10-18 kg in air which is 0.1% supersaturated; contains 10 …

An 18-kg cannonball and a 12-kg cannonball are chained together and fired horizontally with a velocity of 165 m/s from the top of a 15-m wall. The chain breaks during the flight of the cannonballs and the 12-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire.
