Answer:
its Y because the dot that represents it is close to S
Answer:
Explanation:
consider the principle of moment
when a system is in equilibrium, the clockwise moment (torque) about the pivot is equal to the counterclockwise moment ( torque). Since the plank is uniform the weight of the plank act at the middle which = 6.1 m / 2 = 3.05 m
the distance that can support the weight of the man = d
mass of the man = 70
70 × d = 33 × ( 3.05 - 1.6)
d = 47.85 / 60 = 0.798 m, if the man work beyond this point he will fall.
Explanation:
i really didn't understand the question
im soo so sorry
Answer:
<h3>
given</h3>
To find - Value of the equation
Solution -
5x + 40
Putting value of x = (-5) in equation
5(-5) + 40
-25 + 40
15
(a) The momentum of a moving object is given by:

where m is the mass of the object and v is its speed. In this problem, the mass of the elephant is
and its speed is
, therefore its momentum is

(b) We can use the same formula to calculate the momentum of the tranquilizer dart, whose mass is
and whose speed is
:

we see that the elephant's momentum is much larger than the momentum of the dart.
(c) Again, using the same formula, the mass of the hunter is
, his speed is
, therefore his momentum is
