Answer:
Force,
Explanation:
Given that,
A potential energy function for a system in which a two-dimensional force acts is of the form of :
We need to find the force that acts at the point (x, y). The force in 2 dimensional with components is given by :
So, the force acting at the point (x,y) is . Hence, this is the required solution.
Answer:
a)H=84.87 m
b)R=565.27 m
Explanation:
Given that
Speed of ball on earth
U=41.2 m/s
θ=31°
We know that
Maximum height in projectile motion given as
h=22.94 m
Range in projectile motion given as
r=152.77 m
Given that on distance planet ball moves 3.7 times far more as on earth.
So on the distance planet
The maximum height ,H=3.7 h
H= 3.7 x 22.94
H=84.87 m
The range on distance planet
R=3.7 r
R=3.7 x 152.77 m
R=565.27 m
Answer:
N = 648.55[N]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
∑F = Forces applied [N]
m = mass = 73.2 [kg]
a = acceleration = 0.950 [m/s²]
Let's assume the direction of the upward forces as positive, just as if the movement of the box is upward the acceleration will be positive.
By performing a summation of forces on the vertical axis we obtain all the required forces and other magnitudes to be determined.
where:
g = gravity acceleration = 9.81 [m/s²]
N = normal force (or weight) measured by the scale = 83.4 [N]
Now replacing:
The acceleration has a negative sign, this means that the elevator is descending at that very moment.
Answer:
25
Explanation:
Given:
1 can of concentrate requires 3 cans of water
Now,
Total ounces in 200 6-ounce cans = 1200 ounces
also,
for 1 can of concentrate requires 3 cans of water
thus,
for 12 ounces can water can required = 3 × 12 ounces = 36 ounces of cans
Thus,
total ounce of juice per can = 12 + 36 = 48 ounces per can
therefore,
the number of 12-ounce cans required are =
or
=
or
the number of 12-ounce cans required are = 25
