Question

Three different objects, all with different masses, are initially
at rest at the bottom of a set of steps. Each step is of uniform
height d. The mass of each object is a multiple of the base
mass m: object 1 has mass 4.60m, object 2 has mass 1.71m,
and object 3 has mass m. When the objects are at the bottom
of the steps, define the total gravitational potential energy of
the three-object system to be zero.
Each answer requires the numerical coefficient to an
algebraic expression that uses some combination of the
variables m, g, and d, where g is the acceleration due to
gravity. Enter only the numerical coefficient. (Example: If the
answer is 1.23mgd, just enter 1.23)
If the objects are positioned on the steps as shown, what is
gravitational potential energy Ug,system of the system?
If you redefine the reference height such that the total
potential energy of the system is zero, how high ho above the
bottom of the stairs is the new reference height?
Now, find a new reference height h (measured from the base
of the stairs) such that the highest two objects have the exact
same gravitational potential energy.

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. Each step is of uniform height d. The mass of each object is a multiple of the base mass m: object1 has mass 4.00m, object 2 has mass 1.96m, and object 3 has mass m. When the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. If the objects are then relocated as shown, what is the new total potential energy of the system? Each answer requires the numerical coefficient to an 2 algebraic expression. Each algebraic expression is given using some combination of the variables m, g, and d, where g is the acceleration due to gravity. Enter only the numerical coefficient.

Q5. The 9-kg ball is connected to a spring with spring constant k = 240 N/m and unstretched length of 0.8 m. Initially the spring is compressed and has length 0.5 m. Then under the constant applied force F= 200 N (in the direction shown in the image) acting on the ball, the spring is stretched to a new length 1.5 m. Determine the work done by weight to the ball during this process. The slope is smooth. Please pay attention: the numbers may change since they are randomized. Negative sign must be included if the work done is negative. Your answer must include 1 place after the decimal point, and proper SI unit. Take g = 9.81 m/s². M Your Answer: Answer 40° units F 15°
