a cyclist must travel 800 km. how many days will the trip take if the cyclist travels 8/h day at an average speed of 16km/h
sergey [27]
It would b 6 days and 6 hours
You would times 16 by 8 which gives 128km a day. To find how many days you would divide 800 by how many kilometres they cover a day which is 128
So 800/128 =6.25 which converts to 6 days and 6 hours.

34000×0.4<br> ----------------<br> 0.02×200<br> In scientific notation
VashaNatasha [74]

Answer:

the simplified expression is written as 3.4 x 10³

Explanation:

Given expression;

\frac{34000\times 0.4}{0.02 \times 200}

in scientific notation, the expression is simplified as;

\frac{34000\times 0.4}{0.02 \times 200}  = \frac{13600}{4} = 3400 = 3.4 \times 10^3

Therefore, in scientific notation, the simplified expression is written as 3.4 x 10³

How does gravity affect space travel?
IceJOKER [234]

Answer: Think of it like this, in space there is no gravity. This makes it very hard to move. This is why spacesuits have mini propellers. And the reason why rockets well... have rockets.

A 4.75 kg block is sent up a ramp inclined at an angle ????=31.5° from the horizontal. It is given an initial velocity ????0=15.
Colt1911 [192]

Answer:

d = 13.7 m

Explanation:

When block is moving upwards along the inclined plane

then the block is decelerated due to gravity as well as due to friction and speed of the block by which it is projected upwards is given

v_i = 15 m/s

deceleration caused to the block due to net force opposite to the motion is given as

F = - mg sin\theta - \mu mgcos\theta

a = \frac{F}{m}

a = -g(sin\theta + \mu cos\theta)

since block is sliding on the inclined plane

so here we can say that the coefficient of the friction must be kinetic friction here

a = -9.81(sin31.5 + 0.368 cos31.5)

a = - 8.2 m/s^2

now for finding the distance upto which it will stop is given as

v_f^2 - v_i^2 = 2 a d

0 - 15^2 = 2(-8.2) d

d = 13.7 m
