(h + .16) m g = 1/2 k x^2 total PE of block relative to where it stops
(h + .16) .82 * 9.8 = .5 * 120 * .16^2 PE released = PE of spring
8.04 h + 1.29 = 1.536
h = (1.536 - 1.29) / 8.04 = .031 m = 3.1 cm
What’s the question though
Answer:d
Explanation:
Eiffel tower is made up of puddling of cast iron and trusses to provide fire-resistant material. Around 7000 metric tons of puddling iron is used to construct the Eiffel Tower. The structure composed of four large arched legs, upright on masonry columns that joined to become one.
Effiel tower uses the criss-cross beams structure called trusses which provide strength to the structure. The strength comes from the inherent stability of triangular structures.
Answer:
Option D
48 N
Explanation:
From Newton's law of motion we deduce that the magnitude of force is a product of mass and acceleration hence expressed as, F=ma where F is the magnitude of force, m is the mass of the object and a is the acceleration of the cart. Substituting 24 kg for m and 2 for acceleration then
F=24*2= 48 N
