A 3-kg mass is attached to a spring with stiffness k = 48 N/m. The mass is displaced 0.5 meters to the left of the equilibrium point given a velocity of 2 m/sec to the right. The damping force is negligible. • Find the equation of motion of the mass along with the amplitude, period and frequency. • How long after release does the mass pass through the equilibrium position?

w'x is 0.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
