1 answer:
As the box sits at the top of an incline that is 50.0 cm tall and makes an angle of 25° with the ground, The time it takes to reach the bottom of the incline is mathematically given as
t=0.148s
<h3>What is the time it takes the box to reach the bottom of the incline?</h3>Generally, the equation for the acceleration is mathematically given as
Therefore
a=(9.8sin-(0.15cos35))
a=4.417
Thereofore
v^2=v0^2+2al
v=2.6533
In conclusion, The time t is
t=v-v0/a
2.65-20/4.417
t=0.148s

Answer:
The appropriate solution is "61.37 s".
Explanation:
The given values are:
Boat moves,
= 10 m/s
Water flowing,
= 1.50 m/s
Displacement,
d = 300 m
Now,
The boat is travelling,
=
=
Travelling such distance for 300 m will be:
⇒
On putting the values, we get
Throughout the opposite direction, when the boat seems to be travelling then,
=
=
Travelling such distance for 300 m will be:
⇒
On putting the values, we get
hence,
The time taken by the boat will be:
=
=
