Find Displacement and Distance
displacement ...
north is 700+400+100 =1200m n
south=1200m
1200-1200=0
east is 300+300=600m
west is 600m
600-600=0
back at dtart. displ zero
distance is 700+ 300m + 400 m + 600m + 1200m + 300m + 100m = 3600m
Answer:
E) True. Ball B will go four times as high as ball A because it had four times the initial kinetic energ
Explanation:
To answer the final statements, let's pose the solution of the exercise
Energy is conserved
Initial
Em₀ = K
Em₀ = ½ m v²
Final
Emf = U = mg h
Em₀ = emf
½ m v² = mgh
h = v² / 2g
For ball A
h_A = v² / 2g
For ball B
h_B = (2v)² / 2g
h_B = 4 (v² / 2g) = 4 h_A
Let's review the claims
A) False. The neck acceleration is zero, it has the value of the acceleration of gravity
B) False. Ball B goes higher
C) False has 4 times the gravitational potential energy than ball A
D) False. It goes 4 times higher
E) True.
~Formula: Voltage= current• resistance
(V= Ir)
~Using this formula, plug in the numbers from the equation into the formula
~5=25i
~Now you have a one-step equation
~Divide by 25 on both sides and you should get your answer:
~I= 0.2 (which means current is 0.2)

Explanation:
Eg = mgh
a. Eg = (2.00 kg) (9.8 m/s²) (12.0 m)
Eg = 235 J
b. Eg = (2.00 kg) (9.8 m/s²) (3.00 m)
Eg = 58.8 J
c. Eg = (2.00 kg) (9.8 m/s²) (4.50 m)
Eg = 88.2 J
d. When the coconut hits the bystander:
Ek = 235 J − 58.8 J = 176 J
When the coconut hits the ground:
Ek = 88.2 J − 0 J = 88.2 J
Ek is the greatest when the coconut hits the bystander.
