A hiker walks 9.4 miles at an angle of 60° south of west. Find the west and south components of the walk. Round your answers to
Tanzania [10]

Answer:

The west axis component of walk is, A = 5 miles

The east axis component of walk is, B = 8 miles

Explanation:

Given data,

The displacement of hiker south of west, R = 9.4 miles

The angle formed south of west, Ф = 60°

The vector components along,

                   the west axis is

                                      A = R cosФ

                                       A = 9.4 x cos 60

                                       A = 4.7 miles

                                        A = 5 miles

The west axis component of walk is, A = 5 miles

                    the south axis is

                                      B = R sinФ

                                       B = 9.4 sin 60

                                        B = 8.14 miles

                                         B = 8 miles

The east axis component of walk is, B = 8 miles

If an astronaut travels to different planets, which of the following planets will the astronaut’s weight be the same as on Earth
Nataly_w [17]
<h2>Astronaut travels to different planets - Option 4 </h2>

If an astronaut travels to different planets, none of the planets will the astronaut’s weight be the same as on Earth. On jupiter, weight will be more than the weight on earth. For instance if an astronaut has 100kg on earth then he will have 252 kg on jupiter.

On Mars, weight will be less than the weight on the earth. For instance, if an astronaut has 68 kg on earth then he will has 26 kg on mars. On Mercury, weight of an astronaut will be less than the weight on earth. Example if he has 68 kg on earth then he will have 25.7kg on mercury.

Hence, none of these planets the weight of astronaut will be same as on earth.

A runner of mass 51.8 kg starts from rest and accelerates with a constant acceleration of 1.31 m/s^2 until she reaches a velocit
Stells [14]

Answer:32.24 s

Explanation:

Given

mass of runner (m)=51.8 kg

Constant acceleration(a)=1.31 m/s^2

Final velocity (v)=5.47 m/s

Time taken taken to reach 5.47 m/s

v=u+at

5.47=0+1.31\times t

t=\frac{5.47}{1.31}=4.17 s

Distance traveled during this time is

s=ut+\frac{1}{2}at^2

s=\frac{1}{2}\times 1.31\times 4.17^2=11.42 m

So remaining distance left to travel with constant velocity=153.57 m

thus time =\frac{distance}{speed}

t_2=\frac{153.57}{5.47}=28.07 s

Total time=28.07+4.17=32.24 s
