A skier skies down a slope with an average speed of 50 km/s. How far does the skier travel in 5 minutes?
aliya0001 [1]

Answer:

15000000 m

Explanation:

From the question,

Speed (S) = Distance(d)/Time(t)

S = d/t....................... Equation 1

Make d the subject of the equation

d = St..................... Equation 2

Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds

Substitute these values into equation 2

d = 50000(300)

d = 15000000 m

Hence the skier travels 15000000 m

An object has a mechanical energy of 1575 J and a potential energy of 1265 J.
laila [671]

6.  

A. 1575 - 1265 = 310J

B.  KE 1/2 MV^2

   V=√2·KE/M = √2(310)/12   V = 7.2mls

C.  PE = 1265 = mgh

h= 1265/mg = 1265/(12)(92)    h= 10.8m    

7.  

A.  KE  = 1/2 mv^2  0.5(5)(12)^2    KE = 360J

B.  PE = mgh = (5)(9.8)(2.6)  PE = 127.4J

C.  ME = KE + PE = 360 + 127.4   ME = 487.4J

2 Magnetism comes from the word
AysviL [449]

Answer:

A Magnesia

Would this be 2N because 6 and 4 cancel out? Or no because 4 plus two is six and that cancels everything out to 0
soldier1979 [14.2K]

Answer: It would be 0

Explanation: Because like you said it would cancel each other out because if you are going 6N to the right and then you go 6N to the left you are actually not moving at all
