Answer:
x = 102.33 m
Explanation:
Given that,
Position where a forest ranger stands is 35 m above the ground. The angle of depression to the base of the fire is 20. We need to find how far from the tower is the fire.
Let the distance is x. We can find x using trigonometry as follows :
Hence, the fire is at a distance of 102.33 m from the fire.
The force is 1.5N acting downward or -1.5N.
Why?
To answer this question, we need to remember the Newton's Third Law. This Law states that for every force applied upon an object, there is an equal force acting in the opposite direction. This Law is also called "action-reaction Law".
So, if the force of the players heads applied on the ball is equal to 1.5N (upward), the force applied by the force on the players heads will be exactly equal, but with opposite direction, or -1.5N (downward).
Have a nice day!
Answer:
1.60217662 × 10(-19) coulombs
If the car is moving west, then the only way to stop it, or even just slow it down, is with a force that's directed <em>toward the east</em>.
To solve this problem we will use the Force equation according to the definition given in Newton's second law. There we have that the Force is equal to
Where,
m = mass
a = acceleration
Our values are given as
Considering that both mass are equal to one, we have that:
Therefore the truck exert a force on the car of 11kN
