Missy's velocity is 24.5 m/s
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion. Mathematically, it is given by
where
m is the mass of the object
v is its velocity
In this problem, we know:
K = 15000 J is Missy's kinetic energy
m = 50 kg is her mass
Solving for v, we find her velocity:

Answer:
<em>The apple's potential energy is 0.9555 Joule</em>
Explanation:
<u>Gravitational Potential Energy</u>
Gravitational potential energy is the energy stored in an object because of its vertical position or height in a gravitational field.
It can be calculated with the equation:
Where m is the mass of the object, h is the height with respect to a fixed reference, and g is the acceleration of gravity, or 9.8 m/s^2.
The apple has a mass of m=0.15 kg and it's located at a height of h=0.65 m. Calculate the potential energy:
The apple's potential energy is 0.9555 Joule
Answer:
a) Displacement of the object from t = 0 to t = 3 is 1.5 m
b) Distance of the object from t = 0 to t = 3 is 1.83 m
Explanation:
Velocity, v(t) = t² - 3t + 2
a) Displacement is given by integral of v(t) from 0 to 3.
b) t² - 3t + 2 = (t-1)(t-2)
Between 1 and 2, t² - 3t + 2 is negative
So we can write t² - 3t + 2 as -(t² - 3t + 2)

Answer:
The current is halved
Explanation:
The relationship between the current and the resistance is given by Ohm's Law, as follows:
where,
V = Voltage
I = Current
R = Resistance
Therefore, if we double the resistance:
Hence the correct option is:
<u>The current is halved</u>
