The average acceleration is the change in velocity divided by change in time.
Answer:
2. at the highest point
Explanation:
For a generic object, the PE (gravitational potential energy) is defined as
PE = mgh
where
m is the mass of the object
g is the gravitational acceleration
h is the height of the object with respect to the ground
From the formula, we see that PE is maximum when h is maximum: so the PE is maximum when the object is at the highest point.

Solución
La velocidad instantánea está dada por,
v = dx / dt = pendiente de la curva x-t
aquí, del gráfico:
en x = 1 m ---> t = 8 s
en x = 3 m ---> t = 0 s
entonces, dx = 1-3 = -2 m
dt = 8-0 = 8 s
Entonces,
v = -2/8
v = -0,25 m / s
Dado que, pseed es una cantidad escalar.
Entonces, velocidad instantánea = | v | = 0,25 m / s
~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)
