Explanation:

Potential energy at the top of the slide

PE = mgh = 49(9.8)(3) = 1,440.6 J

Energy converted to work of friction

W = Fd = 35(10) = 350 J

Converted potential that becomes kinetic energy

1440.6 - 350 = 1090.6 J

KE = ½mv²

v = $\sqrt{2KE/m}$

v = $\sqrt{2(1090.6)/49}$

v = 6.671902...

v = 6.7 m/s

Which statement is a correct expression of the Law of Conservation of Mass?

DiKsa [7]

<span>The correct answer is B. The law of conservation of mass states that the mass of an isolated system is neither created nor destroy by chemical reaction or physical transformation. This means that the mass of subtances in an isolated system remains constant, it can not decrease and it can not increase.</span>

A spaceship is 1600 m long when it is at rest. When it is traveling at a certain constant speed its length is measured by extern

Firdavs [7]

Answer:

speed of the spaceship is 0.495251 c

Time T = 1.4982 hr

Explanation:

given data

length L1 = 1600 m

length L2 = 1390 m

to find out

speed of the spaceship and time

solution

we know here

L2 = L1 × $\sqrt{1 - V^{2} }$

so we find V by put L1 and L2

1390 = 1600 × $\sqrt{1 - V^{2} }$

V = 0.495251 c

speed of the spaceship is 0.495251 c

and

we know T1 = 1.95 hr

so we find T2

T1 = T2 $\sqrt{1 - v^{2} }$

put here V and T1 so we get T2

1.95 = T2 $\sqrt{1 - 0.495251^{2} }$

Time T = 1.4982 hr
