Aperson cannot see clearly objects closer than 2.00 m from her/him. what is the refractive power (in diopters) of the correction lenses that will allow her/him to clearly see objects located 30.0 cm, but not closer, from her eyes? ignore the distance between her/his eyes and the lenses.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
