A 76.5 kg cross-country skier skiing on unwaxed skis along dry snow at a constant speed of 4.00 m/s experiences a force of friction of -60.0 N.  What is the coefficient of friction between unwaxed skis and dry snow?a. 0.08
b. 0.78
c. 1.28
d. 12.5

Answers

The force of friction = (weight) x (coefficient of friction)

Skier's weight = (mass) x (gravity) = (76.5) x (9.8) = 749.7 N

Force of friction = (749.7) x (coefficient of friction) = 60.0 N

Coefficient of friction = 60 / 749.7 = 0.08  (rounded)

Objects dropped straight or thrown horizontally from the same height
change their vertical velocity at the same rate, and fall through equal
vertical distances in equal time intervals.

The statement is false.

A car climbs 10.0 kilometers up a hill that inclines 8.0 degrees. What is the car's vertical displacement?

Answers

The correct answer to the question is : 1.392\ Km

CALCULATION:

The angle of inclination of the hill with the horizontal ground \theta =\ 8^(0).

The magnitude of displacement  or the distance travelled by the car up that hill is given as -

                        distance S = 10.0 Km.

We are asked to calculate the vertical displacement.

Applying vector resolution process, we get-

(a) Scos\theta is the horizontal component

 (b) Ssin\theta is the vertical component.

Hence, the vertical displacement is calculated as -

                        Vertical displacement S_(y) =\ S\sin\theta

                                                                    =\ 10* sin8^(0)

                                                                    = 1.392 Km.

Hence, the vertical displacement of the car is  1.392\ Km
